CAD thread? CAD thread.
>>993073 (OP)which CAD software should I invest my time in?
>>993073 (OP)Plasccity trial expired can't use it anymore, I feel sad
I actually did some stuff in FreeCAD with zero CAD knowledge. I hit a lot of bugs but it did work.
>>993112How could you be so sure they were bugs if you entirely lacked any prior knowledge?
>>993073 (OP)For me, it's Autodesk Inventor with 30% extra session crashing.
>>993237>shit crashes>shit explodes (constraint solver finding a solution that's not a solution)
>>993073 (OP)Tried 123design it's shit
>>993102Once you trial it that's it, developers made s tier security and it's uncrackable
Freecad is a weird combination of totally usable and frustratingly limiting. I am able to design most of what I need (fairly simple stuff though) but as soon as I try to do something in an order it doesn't like, the whole thing crashes. Will be nice in 5-10 years I think.

Every problem involving contact interactions has been a pain so far. I'm not even mad anymore.
>>993073 (OP)>>993287nothing is uncrackable, he just paid crackers not to crack it
As an outsider I HATE 3d software.
Why do I need to install some arcane software whos GUI is build by fucking brain damaged people to do one fucking thing?
In this case engraved text on a curved surface.
Why can't these fuckwits make even importing models intuitive?
I made this in autocad btw and want text on the curved recess.
I'm attempting to use inventor but this shit is maddening.
>>993097fucking none. learn a trade instead because shit is built by fucking twisted retards.
Autocad is ok
>want to insert a file into current document?
Hit OPEN. WTF fucking zoomer devs you total Cumbrians

I will murder on sight any 3D software dev I meet
Meltie over for now
>>993587I've managed to make a few things with freecad with it being the only cad software I've used. But it seema like I can never continue working on a saved project once it has been closed and reopened, nothing ever works again. I have to treat it like an 8bit videogame and complete it in one sitting.
It is incredibly satisfying when you actually get that cumbersome hunk of shit to make something slick though.
I feel bad for people who don't use Catia
>>993097for me rhino, expensive as hell but easy to get around if you willing to renew the 3 month demo version with a different email each time lmao
>>993287>>993745I can crack it if you pay me.
>>994424how much do you want?
>>993705I deal with SW Simulation as a job, and I hate it with a passion, I tried asking management to get an Ansys license to no avail because it costs too much and there's not enough demand.
Going back to SW Simulation, first off the progress bars mean nothing, seriously, they barely qualify as vague suggestions. Secondly if your simulation runs for 5 hours and then fails you've got a stupid fine mesh while the analysis isn't properly modeled. Try with a VERY coarse mesh first, see if it runs, see if the results make sense; then, when you know it runs, use a finer mesh or, better, add mesh controls on the surfaces and edges you want to see in more detail.
If it fails, well I got a whole spreadsheet of errors and failures, full of possible causes and possible solutions, so I can't help you there without more informations.
To be clear, solve time doesn't mean the simulation is fucked, I had simulation run for 25 hours (it was an entire electric motor for an e-bike) and produce good results, but it all comes down to what you're analyzing and how you set up the simulation.
I'm going to use Blender to do CAD work again because learning another software is a pain
>>993792Texturing with a displacement map would be way easier. You don't really see this type of process in real life machining because it's extremely complicated to perform.
>>994663Not sure, it's an electron app LMAO.
>>994671I need to do this to because converting files between programs is making me ultra-violent.
How hard is it to align objects? This is the most basic function I need speaking as the autoCAD psycho above.
Itโs so unintuitive but I just want to zero in any shape I make and move by integer on an axis. Thatโs it.
Now every time I add a bolt connector in sw simulation the document units switch to meters. What the actual fuck. Every default I'm aware of is set to mm.
>>994667In my experience coarse mesh fails the study more often than not, or at least yields questionable results. Fine mesh not so much aside from when solution takes so much time that I get tired of waiting and cancel it myself.
In that particular case the issue was probably parts slipping against each other under load (it was actually the point of study to see if they will), but instead of prompting about large displacement like usual, the solver decided to bug out for some reason.
>>995022>every time I add a bolt connector in sw simulation the document units switch to metersThat's a new one.
>coarse mesh fails the study more often than notNot to backpedal, but I meant "coarse" in a relative way, which is always dependant on the problem at hand. In any way, a failure after 5 hours is usually a symptom of bad modeling and mesh issues. Ideally you want that failure to happen much faster so you can troubleshoot your mesh (check for high aspect ratio elements, negative jacobian, shit base geometries, etc) more efficiently.
>parts slippingConctact analysis is a bitch in SW, getting it to behave requires esoteric knowledge not even Dassault has. Be mindful about the sleazy trick SW plays on us every time you mess with the model and then go back to the simulation: it may automatically switch the contact between faces you had previously defined to a self-contact, which usually doesn't work when you have two different bodies. I have wasted DAYS of machine time on this shit, fucking hell. Also, if you're studying slipping I assume you set a proper friction coefficient, but keep in mind SW doesn't like very high coefficients, and on the other side of the spectrum it won't go below 0,05.
Also, what's your usual node count? My workstation at the office is a somewhat recent Xeon with 128GB of ECC memory and a proper nvme drive, and I try staying below 3~4 million nodes at most (an analysis like that takes from 10 to 25 hours), and below 1 million if I can help it, with running times in the order of 4~8 hours; less than 500 thousand if I want something to shit out results within the day; if the problem allows it, I can use less than 200 thousand nodes if I want it to finish in a matter of minutes.
>>994663$120, the code is compiled using bytenode, it's hard to decompile and the file seems to have an extra layer of obfuscation on the top.
>>995037>a symptom of bad modeling and mesh issuesFor one, that model had lots of unnecessary details that now that I think about it could be simplified or cut out altogether.
>it may automatically switch the contact between faces you had previously defined to a self-contactAh so that's what it was. I had a really cursed study a while ago where either some contacts would fall through each other for no obvious reason, or the study would fail due to "numerical difficulties". That's what probably was happening. Good to know.
>keep in mind SW doesn't like very high coefficientsThe real coefficient would be at least 0.3, and the max 0.2 sw takes without complaints should've been just barely enough in theory (under the assumption of uniform contact pressure - which it isn't, hence the study) so the idea was that if 0.2 will work then the real thing will work even better.
>Also, what's your usual node count?I don't really pay attention to that. I usually just tune mesh size by feel depending on how much time I'm willing to spend on it. Solution time can vary wildly depending on number of contacts and how well the model behaves after all. The study right now with 750k nodes, with every contact that have to watch out enabled just finished in 4.5 hours. With only essential contacts that move by design it takes 1h 40 min. With everything bonded it finishes in under 7 minutes. I'm running it on i5-12400, in a VM with 24 Gb of ram.
When I'm just fiddling with stuff I usually try to keep the solution time under half an hour, and only run longer studies when I want to verify the final design that I'm reasonably sure I won't have to fix and run again.
any fusion chads here? also i write websites in php and use an iphone. feels good to get paid and watch you nerds squeal over tools lmao
>>993705>>994667Have you tried Catia V5? I have an old R20 somewhere.
The V5 is the standard for Airbus and our aviation business overall.
SW is honorable but it's not as powerful.
>>995164How do i contact you?
>>995885>>994667 here. I work in a studio, we have all the softwares so whatever our client has, we can work with it too. I've seen CATIA, but never used it. UI is shit, and that's pretty much all I can say about it. As for the "powerful", I think it all comes down to handling large assemblies with millions of components and integration with a robust PDM that might set it apart from everything else. As for actually modeling in it, I don't know, but one of the good thing about SW is that being so widespread there's always something online that will help you learn or solve a situation, while the same can't be said about CATIA. In the end all CAD work pretty much the same (more or less). Just today I was reading SW2025 highlights and my impression is that DS is doing basically the absolute bare minimum to keep all these softwares afloat, because SW works like absolute ass, but the features and fixes are so few and far in between to be laughable. Also, unless you work in some massive corporation that does massive projects it's infinitely more likely for you to encounter SW than CATIA.
Plasticity user here. How can I start learning to make AAA quality firearms? I know modeling in general fairly well but guns have been quite difficult for me in CAD software. Any good pirated courses? What guns should I create as a beginner?
Is there a CAD package that
>is cheapish (max $500/yr, inb4 pirate)
>has parameters that integrate with Google Sheets/Excel
>has text parameters that can be imported to a model/2d geometry
>has g-code export (not a need, but a nice to have)
I want to do a little sign business out of my garage. Ideally I would have products that are customizable without having to go in and change the model with each iteration.
I want to be able to put Basic Girl's(tm) last name/family motto/marriage date w/e into a spreadsheet and have a router table shit out
"(Basic Girl Name) and (Basic Guy Name) married (year) at (stupid town they live in)"
or w/e.
I use Inventor at work, string parameters are abhorrent. I have to do a work around to import text parameters from excel. It's also more than I need for mostly 2d signs.
for me, it's IronCAD. The tri-ball is GOAT
>>998446alibre, probably.
>>998615>>998446Just mucked around with it a bit - they don't do the integration I need.
Currently I have to use an iPart in inventor, and then edit the iPart table in Excel since you cannot populate the regular parameter table with strings from Excel.
I am sure this functionality exists somewhere - how many part configs have different things engraved in them? Surely they don't expect engineers to manually change the engraving for each different part iteration.

>>994890>How hard is it to align objects?It's possible, the features are there, but it's very tedious to do in default Blender without addons
>>998636yeah I think you have to script it in python

In fact I can recommend Rhino to everyone in this thread. One-time payment, no bs subscriptions, not gonna change, whatever you can't do in Rhino, you can do with the Grasshopper plugin, whatever you can't do with Grasshopper, you can do with someone else's extensions to it or write your own.

There was a thread on /g/ a few weeks ago that said Freecad 1.0 was actually pretty good now. I just tested it. It's still shit.
>>993073 (OP)does anyone have good tuts on manually building surface for G2 tolerance?
i tried to get into that shit half a decade ago but between a shit work environment and my own incompetence i bounced off it. thinking about giving it another try, there are a lot of jobs in my area that pay well if i can wrap my head around it
to be clear, not B side or engineering, but for organic sheet surface, like auto industry standard tolerance
also whats the industry standard software these days? catia? we were using alias, how well does that knowledge translate?
>>1001094go on /g/, apple shills are everywhere. The fact that you don't believe that a small startup wouldn't shill their products when a massive marketing agency like apple does confirms that you're a shill.
>>1001103>G2 toleranceTolerances are a specification on a technical drawing, not something you bake in your 3D model. They're an indication for manufacturing.
>industry standard softwareAll of them. If you have to learn from scratch I'd say start with Solidworks which is widely used, easy to learn, and has you have an infinite amount of online resources at your disposal to learn from and troubleshoot any issue you might have. Alternatively I can recommend Onshape (same company behind Creo), which is browser-based, free2play, and very very modern. In the end all parametric CAD softwares share the same core principles, just different UI/shortcuts/gestures.
>>996273did you buy or pirate?
freecad doesnt let you preview anything. you have to know the exact value ahead of time and put them in the left panel instead of a pop up box its also butt ugly. no smooth animation when switching angles. you have to dig through its terrible ux/ui just to change the grid values.
its not a decent alternative specially considering fusion 360 is free.
if you insist on using linyx exclusively then use ondhape atleast.
the only viable way to use freecad is by cutting primitives with the modifier.
dont get me wrong all cad software has clunky gimp tier ux ui but freecad is just the worst.
why cant i scale a segment or a shape in fusion 360 for example. why cant i fillet after using patch? why is the measuribg tool such shit when its so important.
>>998446theres a 3d printer plugin for fusion 360 not sure how good it is
I'm trying to make a quick thing and need to put a uniform indent all the way around on the selected face. Currently using Freecad, how would I do this? The closest thing I could find just clicking around would be the thickness tool, but it makes the indent too deep. Please be patient, am retard.
>>993073 (OP)Is FreeCad usable now?
>indian YouTube tutorial
>Dude just doing an exercise from his school
>Don't use any shortcut
>Leave sketch unconstrained
>You can hear farm animals in the background
>>1002227You may have already gotten your answer in the other FreeCAD thread, but here's an example of one way of doing it. You can define your profile in a sketch, then do a Revolution. In my image, I only did the top half of the profile, so I could mirror it later. You could define whatever crazy profile you need, or just a simple channel.
>>1002338Thank you! This helped a lot.
>>1001630It's a cool thing but gets really slow for more complicated designs. Also, making fillets is pain. I wish there was an OpenSCAD style software that did not have these limitations.

is something like pic possible in freecad? Wondering if I should invest my time setting up Windows again if its not possible with freecad.
>>1001103Do you mean G2 surface continuity? I learnt to surface by fucking around in Solidworks and Rhino and looking at online videos, tutorials and what used to be readily available presentations from Solidworks World. There was also Rhino stuff available but I haven't looked in ages.
I've used Solidworks for about 25 years so biased towards that - I have my own license - and it probably has the greatest userbase. DS are twats, though. Rhino is good but has a slightly different approach which might be familiar if you have used AutoCAD (old versions anyway). Surface building in Rhino is closer to alias than SW. Fusion is actually alright if you aren't doing anything really complex. Can't get on with Freecad but haven't tried 1.0 yet.
Solidworks is used a lot in manufacturing and product design (not always the best tool but ubiquitous) and Rhino in product design, furniture and architecture.
>>1002873Sure why not?
>modeling threadsretarded
>>1002873yes, but it would be painful, I found positioning and interfacing of parts in freecad to be abhorrent.
I've heard that CAD models are the best for 3D printers, but I'm looking to make something with a pretty organic shape and have been told Blender would work way better for that, and then I've heard Blender models aren't great for 3D printing.
Is this accurate?
Is there a specific software that would be ideal for something that needs to be printable but needs smooth curves that would be hard to model with splines or extra planes?
>>1003138>I've heard that CAD models are the best for 3D printers, but I'm looking to make something with a pretty organic shape and have been told Blender would work way better for that, and then I've heard Blender models aren't great for 3D printing.Blender is fine for 3d printing just make sure your mesh has enough detail. Organic shapes might be better off with a resin printer over a FDM style.
>>1003138>mechanical partCAD
>artsy piece of shit toyBlender
Simple as.
>but but but blender can be used for engineering!!!!No, shut up, it can't.
>>1003142I'm doing both, so I'm guessing I should do the mechanical part in CAD and the artsy part in Blender and design them such that the artsy part can be connected with the mechanical parts with glued pins or snaps or screws or something? Can Blender do the precise measurements necessary to align fastening points?
I'm torn right now between learning Blender or trying to find Solidworks tutorials for more organic shapes. I suspect the time commitment is similar, which would give Solidworks the win because then I could test how the shell and the mechanisms articulate together in an assembly instead of printing both out and relying on trial and error.
>>1003159You can import/export meshes into either and cut one part from the other, and cut screw holes from both. The inner part has to be a bit (say 0.4mm) smaller. Blender has an offset solid tool missing from freecad, though for a basic solid freecad's thickness tool can work too. Neither is very controlled so maybe you have to model the hole separately.
>>1003159If you have parametric needs in your organic shapes, Power Surface is an add-on for Solidworks that expands its capabilities for free-form modeling. But I don't know how easy it is to pirate, unlike SW which is piss easy. You're probably better off doing as
>>1003201 said though.
>>1003139>and then I've heard Blender models aren't great for 3D printingI think that's mostly because modelers turn on smooth shading, which does not work for 3D printing, you need geometry
>>1003201>>1003202Thanks for the tips! That information is immensely helpful. I had no idea about the Power Surface add-on or that you could transfer meshes between the two.
>>1003205>smooth shadingThanks for that. I didn't know it was a thing but now that I do I realize it was a staple in entire generations of video games.
>>993073 (OP)I'm thinking about either doing Fusion, Freecad, or Plasdticity. I want to make game/animation assets but also 3D functional objects that work IRL. Whats the best one?
>>1003543For assets go Blender, for 3D functional objects you have to be more specific, but any parametric CAD will essentially work.
>>1003106>>modeling threads>retardedGood way to out yourself as a fucking amateur. I bet your repertoire includes dozens of reddit posts saying that modeling ANY threads is bad, without context.
Look at that image again: the tolerances on the thread diameter are so tight, and the parts so small, that a good engineer/draftsman would model them just to be sure.
>erm... ACKSHULLY I know every ANSI and ISO drill / thread diameter by heartFuck off nigger no you don't.
>>1003789What the fuck are you talking about you retard those are completely normal threads, you write the size in the drawing and the machinist does them to spec and they just work.
Another great thing about not modeling threads is that usually the modelled hole is the correct size for predrill and the outside surface as well so you can easily add predrill size into the drawing as well.
>>1003807Not other anon but modelling for rapid prototyping is common. Just did a load of pipe threads for MJF printed parts that worked very well. Did that to get all threads starting in the correct position and also wanted them working out of the bubblewrap without the user having to faff with taps and dies.
So no, can't always leave threads to the machinist.
>>10038303D printing is a whole different ball game.
And you actually end up having to manually model the threads which would be incredibly wasteful if it were a conventionally manufactured part.
>>1003861Final part will be a moulding or a casting (with a few mods). The print represents almost exactly what the moulding will look like. The casting would be post-machined with threads added afterwards. There's a few arguments to be had over that.
>>1003862Why not thread inserts?
If it large threads like a bottle cap threads then yeah sure mold 'em.
>>1003865Internal threads yes of course where suitable (M5 mounting points) but not so much for external threads or watertight internal threads.
Can I use freecad to build something like a battleship?
>>1003889What scale and level of detail?
Model / rendering purposes yes. Proper ship design uses specialist software or Catia, NX and lots of designers.
What new and interesting things have you discovered for 3d printing? For example I recently found 3dprintable.xyz. What else?
>>1003543Not freecad. Fusion is ok if you're willing to use cloudshit. I prefer plasticity though. And for functional 3d prints, I'd choose that over blender everyday.
>>993097for 3D
Solidworks/Creo

>>1004163if only you knew how bad things really are.
>>1004171Are you approaching this from scratch?
Short form might be:
1. Learn 3D CAD package (whichever you find easiest)
2. Learn about different types of 3D printer and materials (fdm or SLA if home machine, SLS etc if you send out to China or Shapeways etc)
3. Learn rules of designing for 3DP.
4. Take things apart (carefully), look at teardowns (ifixit) to see how things go together.
5. Go print some stuff and see what works, or doesn't. L
6. Iterate.
>>1004194Should probably point out that learning CAD might take a bit of time to be proficient in if you are new to it.
>>1004194yes I guess this should be what i should approach, thanks!
yes I think it would be from scratch, because I haven't found one single person who has some at least some experience on this field
>>1004200any books, resources, threads in here , even plebbit that I should look into?
>>1004311>>1004312Will have a ponder. I have been involved in mech engineering and product design for 30+ years (formal instruction in both) with loads of learning on the job so not the best to suggest a starting point. However:
At a beginner's level, one of my kids is doing DT at school and there's some useful, simple design stuff in the exam revision guides you can buy from book stores.
CAD: FreeCAD and Solid Edge Community Ed are free (certain restrictions on SE). Also openSCAD, which I haven't used and Tinkercad
Fusion 360 and Onshape have or had free plans.
Solidworks has a makers edition which is apparently a PITA with embedded cloud shit. Shame as I use it at work and it is pretty good for what I do.
Some of the packages (Solidworks particularly) have okay built-in tutorials and there are loads of specific examples of functions on YouTube.
One good way of learning is to pick something you have lying around and just start modelling it. Begin with something simple and then increase difficulty. As a guide, blocky stuff like door hinges is easy, organic stuff like detergent bottles is hard. Moving on to take things apart for really in depth modelling will probably teach you more about how things go together than a bunch of books.
3DP: there used to be some best practice guides for FDM available from Stratasys, particularly "FDM for end use parts". Not sure if this has been wiped or stuck behind a registration form now. Simplify3d had a good guide to print settings.
Reddit's r/3dprinting "getting started" wiki has useful bits in it, though usual reddit caveats apply.
There's useful info at hubs dot com resources pages.

and how do I permanently change where the "base point" or "insertion point" of an object is?
I'm used to using turbocad where you just press D and click where you want it to be.
In autoCAD you can change where it is for one operation by pressing B and enter, but then it goes right back to where it was.
there is some CBPR command but you have to install it as a plug-in which is faggy and also it only works on blocks.
Seems like it is missing this very essential feature that I used every day at my old job.

Any resources for learning SolidWorks as a total beginner? I'm doing an internship at a furniture company and my supervisor told me that I should git gud at SW soon, or else he would break my wagie body.
>>1005357SW' own tutorials are a good way to start, and then just look up on the jewtube for more tutorials, but beware of jeets. If you are stuck, try SW' Knowledge Base first (assuming those assholes at the company are actually paying for the license) and duckduckgo second: it's such a widespread software that chances are most of your issues have already been encountered and solved. As a last resort you can ask here, I'll answer when I can.

>>1005369Thanks for the advice. I just started a couple days ago. There is a "200 SW exercises" book I found at anna's archive, just taking it easy with the first couple of models and fiddling around with the sketch and 3d tools.
I was going to watch the CAD/CAM by Mathlaban channel for guidance, but he's a jeet. Do you have any recs for non-jeet youtube channels or good exercise compilations? I think those in the book are okay, but idk how good that kind of practice translates into modelling components for furniture.
>>1005631Any resource is as good as any if you're just starting out. I was half-joking about jeets: I hate how they speak, and that's on me, but the vast majority of their video tutorials won't really help you more than the stuff SW provides you with. That said, I came across good jeet channels, try watching a few videos and decide by yourself what you like best.
Keep in mind that once you grasp the core concepts of parametric 3D CAD (volume generation from 2D, volume addition and subtraction, the feature tree and its order of operation), it all boils down to knowing the advanced tools, keyboard shortcuts, and overall knowledge of the specific software peculiarities.
As for furniture, it depends: in principle you can do anything, but parametric software like SW aren't the best for flowy surfaces, like pic related. I mean: it can be done but it will be time consuming and painful. For basic shit like cabinets, shelves, and tables it's perfectly adequate.
>>1005638Perfectly possible to do flowing, swoopy stuff. You do need to have a good grasp of modelling practices, when to use surfaces vs solids, when to model features directly rather than struggling to get something acceptable out of standard tools (eg fillets).
>>1004322 was me. Furniture has been about 10% of my work over the last 20 years.
Hard surfaces are relatively easy, squishy, irregular upholstery is a pain in the arse to model quickly, but I have learned to use Fusion (sculpt module) for those projects.
>>1005381No that's just Dassault forcing all users on to their system. You will use 3DExperience and you will be happy.
Idiots alienated the most fanatical CAD user base out there.
>>993073 (OP)Used to use Fusion360 but got caught designing a flame-thrower that connected off-the-shelf stock parts together and was banned and all my 250MB of files, includng my robotic hand and assault rifle, wiped.
Cunts and shit happens.
Anything FREE and like Fusion360 that isn't shit and amateurish crap since last I looked?
>>1005972I need parametric that works, since I may need to alter the calibers, leade depth, shoulder angle on cartridges and other chamber specs PLUS I need shit that permits me to have master sketches and from those go to 3d modular design with ease like in Fusio360 but without american twats who will erase MY WORK AND MY DESIGNED as I need them for a patent application and the usa just ensured they won't be fucking getting the manufacturing package this millennia due to their cuntishness.
>I'd rather give it to China than sell it to filthy mericansMy rage is deep, I was raised to know forgiveness is for weaklings and I am not someone to fucking cross.
>>1003993>But really, I dont know why would you just randomly learn CAD.How else is an inventor supposed to try out whether their idea works in 3 dimensions then run the numbers on it in analysis?

Talk sense, kid.

>got banned off Fusion360 a fews years ago and all my work ERASED
I have zero forgiveness... but I've moved on since then, refined the ideas and have something new so in a way it wasn't a total loss.

I just ran with the idea as an exercise. I can always re-do it. It was simple enough. Then the corporate pissflaps spotted it when I was doing stress analysis on the pump housing, somehow.
Got a permaban.
Shit on them.
THEN I found they erased all my designs.
You can imagine how I felt knowing they had simply torched MY WORK, MY DESIGNS, MY FUCKING WORK.
>pleased?
Oh, I'm pretty certain that wasn't it.
No smelly american touches my work.
>>1005976Well... I'm back.
And I have something nice for thee.
>>1005631holy shit. I legitimately screencapped this
>>1005631How did you handle the corners?
I couldn't stay faithful to the dimensions without making them obtuse.
But I guess it's still correct because 90ยฐ wasn't specified in the drawing.
I see some extra faces on yours by the corner so I was just curious
i just had a dream that my cad part bumped up against some other guy's part during shipping and it may have changed the dimensions.
the other designer filled out some kind of incident form before I got a chance to, so then it was my duty to go into the part on my computer and fill out what's called an "updater schedule" to document any kind of deformations that could have happened and manufacturing considerations that may need to change due to it jostling up or whatever with another solid part.
or if the parts became fused how to get them apart.
can anyone with experience tell me if I'd really need to do this because of a shipping accident ?

>>1006519Yeah, I don't think there's any issue with the degree of the corners. No idea of why it ended up looking like that. The sketch was done by mostly abusing the symmetry tool and kind of improving to fit the reference, and then extruding.
>>1005638Thanks anon. I do see that SW isn't commonly used for furniture similar to your pic. Thankfully my company mostly does rectangular shite for banks and offices. Also I'm looking into Rhino 3d in case I need to do more curved stuff.
I do wonder where I can get some exercises for that. I got a pdf with some mock CSWA questions, but they are mostly focused towards mechanical parts, and not furniture components.
>>1007078I got through the first 100 and found plenty of dimensions that were missing or just wrong.
I figure whoever made this was either being a little lazy or went out of their way to simulate the designer experience of being given poor information (which has happened to me many times in the professional world)

>>1007098it's definitely on purpose to force you to look at the picture and reckon what the correct answer is yourself. you can't get wrong values when making such technical drawings out of a cad program unless you manually/deliberately override the text of the dimensions
>>993073 (OP)I made my first complex model lads. What do you reckon?
>>1007513Looks cool anon. I suppose you used an IRL helmet for the dimensions.
In which program did you model the helmet? Any good tutorials for the animation?
>>1007735>animationNTA, but many CAD softwares allow to configure an exploded model of your assembly, and to record an animation of course.
>>1007735Thanks anon, didnโt use a helmet for sizing though did it from scratch. Took a bunch of unflattering pics of myself from various angles and then used them for proportion then measurements for sizing (plus 1-2 thin test prints). Fit turned out great.
I used fusion 360, which handily also has an explosion animator like
>>1007743 mentioned, I think itโs called โanimation environmentโ.
Result turned out pretty good too, pic rel
Which cad software is best for curved syrfaces like those of picrel? I want to try doing more organic forms now that I got some experience with the usual, rigid mechanical components in SW and inventor.
>>1008073Plasticity, hands down. It's cheap too.

I hate this place.
>>1008120I dont need one, I just like to unify my controls between all the different softwares I use, nothing dived me nuts like every God damn 3d software having different controls and fucking up my muscle memory, but pretty much every other software I use has customizable hotkeys, I dont know why this one doesn't, it's such a basic feature, I mean ffs even Microsoft Word will let you customize your keys, it's not rocket science

how is plasticity at handling large/complex files?
most of the tutorials i've seen have been pretty small or simple objects, but how well does this program work with a fully realized mechanical assembly with all sorts of parts, wires, springs, etc like a car or a machine?
does it run smooth or does it chug? my machine isnt a potato but it also isnt top of the line
>>1008331>plasticity>mechanical assembly
>>1008120>>1008130>unironically advocating for 3d miceYou suck at CAD.
A 3d mouse fucking sucks for anything beyond making a smooth pan/rotate to show your boss a cool model.
If your left hand EVER leaves your keyboard then you are slow and inefficient.
I don't care that your $400 accessory has a dozen bindable buttons.
My 5 dollar keyboard has 40+ buttons that can be reached by my left hand, multiplied by every ctrl,shift,alt modifier you can think of.
Every time you click a button on the GUI is time lost.

>>1008922>anything beyond show your boss a cool modelYou'd be surprised how important it is for non-technical people to see nice well presented things, especially when they do not understand them. I know because I learned it the hard way.
By the way you can /diy/ a space mouse for like $20, as long as you already have a 3D printer.
>>1008922>I don't care that your $400 accessory has a dozen bindable buttons.i spent the equivalent of USD50 on it 12 years ago, this isn't a matter of cost
Im not sure if this is the right place to ask because I haven't ever seen a request thread about 3d files, but i was wondering if any anon could help me modify this .stl file?
its a portal 2 floor button. I love this design /thing:3706013
but I wanted it to have a bottom covering it and 2 spaces for keyboard clickers like the model for this one /thing:5078900
Thank you to whoever helps!
>>1008130No that's pretty standard, sadly. I freelance so bring a spacemouse if using my own kit but obviously not always possible.
I bought one of simple two-button ones in 2007 and it died about a year back, so great vfm for the use made of it. Now I have a wireless one that will hopefully see me to retirement.
The old (1990s) tennis ball mice were best to use - cost a fortune back then.
Not necessary but I notice the lack when faffing about in large assemblies or complex geom.

Where can I find blueprints or exercises for SW sheet metal? I want to try modelling one of those old rigid metal cases for desktop computers, but I don't have any laying around for measuring.
>>993073 (OP)Just made my first 3D print in TinkerCAD
:)
>>1009981Google "sheet metal drawings for practice" and look through the image results. Plenty there.
Think I did as you were intending and modelled an old Dell Precision chassis for one of my first forays into sheet metal. It was built like a tank with some interesting clinch fastening (Tox?) going on that was a pain to sort in SW...
>>1010624Slippery slope, anon. Your home will soon be festooned with plastic bits, some of which might be useful...
>>994379Just pirate it bro
>>994379imo Rhino's licensing model is (at least partially) holding back higher adoption. It's very surprising that McNeel hasn't yet offered a free or discounted personal/'maker' version of Rhino, whereas other companies (e.g., Autodesk) have such versions of their programs.
>figured that Plasticity answering the call from Blender's NURBS tools being dogshit for the past two decades would've been enough for old Bob to make his software more affordable, given the popularity that Plasticity generated
For fucks sake, is there really no way to duplicate a sketch in solidworks while keeping all its relations? I'm working out machine geometry and I need to have it sketched in multiple positions at the same time to figure out the rest of design so derived sketches are of no use. Blocks are useless either because they don't support external relations (to this day I have no idea what's their use case at all). Having to restore a dozen or so relations to master sketch dimensioned elements and hinge points each time just because goddamn frenchmen thought that under no circumstances you might have a reason to keep relations on copy-paste is such a huge pain in the ass.
>>1011603copy pasting sketches keep the relations for me. the only thing you should lose is relations to the origin. unless i'm misunderstanding you?
>>1011619to be clear, i'm hitting ctrl+c with a sketch feature selected, then ctrl+v with a target plane selected
>>1011603I add construction line cross hairs, snap to external geom, that I dimension from. Copy sketch to new plane and then re-snap the crosshairs. A pain but doable...
>>1011603You can use blocks as a quick and dirty way of copying geometry from edges converted from a ref model to another model without having to use external references. Example being a pcb hole pattern from an imported connector model, or a standard panel cut.
A other one is layout sketches. A pcb related example is placing boards in a product. Use blocks in sketches and mate pcb assemblies to block sketch elements. Easier and quicker to drag blocks in sketches than faff with mates...
>>1011625>>1011624>>1011619Oh I missed a word, I mean external relations of course. My workflow right now is like this: I draw a master sketch where I dimension all the geometry (simplified using lines and triangles of course) and fix hinge points for movable parts in some eyeballed default position, then draw another sketch where I duplicate the moving parts and use external equal and coincident relations to the master sketch to dimension and fix them properly in hinges and then use some characteristic dimension (like suspension compression height in case of vehicle suspension) or just leave it underdefined to move it to a different position and see if it performs as expected and doesn't do anything weird. I make several of these sketches in different positions then I adjust the master model with movable sketches following the changes to dimensions and hinge geometry while keeping their respective different positions thanks to being related to the master sketch until I'm satisfied with it and can move on to drawing the actual physical parts. For something simple I actually draw all the relevant geometry within the same sketch several times in different positions and then with the right constraints SW automagically derives the proper geometry, but it becomes overcluttered really fast (pic related) and also there seems to be some sort of hardcoded calculation time or complexity limit where SW would just throw the towel and mark everything red as unsolvable even though you can still fiddle it in place manually (until the next tiny change or even just rebuild where it blows up again). So for more complex stuff several identical sketches all related to the main sketch, just with one or few dimensions adjusted later become a necessity.
>>1011652>Comment too longDerived sketches don't work for this because they're all identical to the original, you can't make individual changes to the copies; blocks are pretty much the same but even worse because they can't have external relations at all so the entire thing must be defined within the block and it's simply not feasible when it's not an already completed part you have to work around but a part of a larger model you're designing.
p.s. just had an idea as I was writing this, maybe you can use configurations to wrangle the derived sketches in several different positions at the same time? Will have to test this when I get to my machine.
>>1011652>So for more complex stuff several identical sketches all related to the main sketch, just with one or few dimensions adjusted later become a necessity.And forgot to add that all the external relations to the master sketch are lost on copy-paste so you have to restore them manually for each copy which makes it a great pain that has no reason to exist in the first place
>>1011653>maybe you can use configurations to wrangle the derived sketches in several different positions at the same timeOk tried it and it's a complete shitshow. 1. You can't have several sketches derived from different configurations of the same original sketch within the same part. They simply don't have a configure option. 2. You can't even do this in assembly. Every derived sketch follows the configuration the original part currently has. 3. You can do it in assembly if you copy-paste several copies of the same part that contains the master sketch, set the copies to different configurations, and derive sketches from each of them. They even properly follow changes to the master sketch since it's the same in every configuration. But it's a huge clusterfuck at this point and I'm not sure if it's usable in practice.
>>1011652what are you actually trying to do?
i wouldn't call myself an expert in solidworks even though i've used it for many years (not formal training, just figuring it out as i go)
i have done a few things where i need different elements to line up in different positions, like a machine which can be operated at several angles, requiring pin holes to match up at each angle. initially i did this using a sketch, but now i do it using copies of the moving part(s) and setting them as envelopes. i can attach things like holes to said envelopes as external references without needing to draw messy sketches
>>1011692-- also in general i've learned that solidworks doesn't particularly like "equal" and "tangent" relations, i've greatly reduced situation where large sketches suddenly go completely yellow by keeping those to a minimum
>>1011692>what are you actually trying to do?Not sure what to answer to that aside from what I've already said. I'm using sketches to derive the basic geometry of moving machinery, like vehicle suspension, a small excavator arm (on the pic above), or a laser beam positioning system I'm working on right now, and I have to make several copies of said sketched geometry in different positions to see that nothing weird is happening (like a laser beam missing a mirror in one of extreme positions) while I adjust the model to achieve desired results. I don't have professional SW training either so maybe there's a different way of doing that I'm just not aware of, but I'm yet to find evidence of any.
>>1011702I get what you need, and I too use sketches that way sometimes, but Solidworks' Motion tab should allow you to calculate the various positions of a kinematic system, it might be straight up faster to just go back and forth between the two tabs than trying to wrangle SW into submission when complexity increases. Either that or use a different software.
>>993782>>993792CAD software is for engineers by engineers. I've gotten into it as software engineer and it hurts my brain since the approach is different, but same base concepts. [spoiler]Go for more geometrically simplistic designs and play with the software to get a better understanding of how to use it.[/spoiler]
>>1011707I use motion too at later stages of the design process but it requires quite a bit of setup, and I sometimes don't even have a clear idea what the thing I'm making will end up looking like when I'm only starting with it. Throwing together a quick sketch in like 10 minutes is often easier and more productive. SW is the best tool I know for this, it's just this one thing with external relations that makes this unnecessarily tedious for no reason.
Anyone use progromatic CAD? I tried out CADQuery cause I'm already familiar with Python but then found out that it's basically been superseded by Build123D so I guess I should learn that instead? Or is there something else I should look into? Seems hard to find information about this niche.
is the fem workbench on freecad useless? Trying to compare some simple pressure load results and it sucks hard.

>>1012887it's more of a donation system. looking at their faq, it's also foss, they just charge for the binaries. this is a perfectly legitimate way to monetise foss. you can build it yourself
>>1012889>they just charge for the binariesNot the first project that does this. Making builds for windows and mac is a PITA (as a programmer I want to kill myself ever time I have to touch windows or mac), so I'd approve of this model even if offering binary builds was the only thing they did.
>>1012890yea, i was going to add that this isn't even that uncommon, but i figured that could be inferred. like for example you can in many cases find programs on the google play store or apple's equivalent where they charge for it even though they're completely foss. people are willing to pay for the convenience
that and of course building for windows is something i can understand wanting to be compensated for, and things like the apple store literally costs money to publish on
>>1012889>you can build it yourselfI'm an engineer, not a /g/entooman, I have no idea how to do that. That said, from a purely ideological standpoint, if they keep it FOSS then I'm less against the asking price. Might give FreeCAD a try, I'm getting kinda pissed at OnShape's retarded way of handling way too many things (although some features are very neat), and if it's not completely trash I might even toss those guys my money for the privilege of being a mere user.
>>1012894>/g/entoomanis it that obvious?
>if they keep it FOSS then I'm less against the asking price.that is why i checked. i haven't heard of this one before.
>I have no idea how to do thatthat's ok, that is expected as well, it's part of the incentive/convenience. if everyone knew how to do it to the extent that it didn't matter if they provided .exe installers or not, it wouldn't be much of an incentive.
keep in mind software freedom as far as the FSF is concerned is only about the availability and license of the source code, they aren't concerned with paywalling binaries (if you even provide them at all. many projects don't provide binaries whatsoever), as that's a service independent of the availability of the source code. not their business.
Fuck it, I'm just going to learn FreeCAD and try to stick with it. Not like I'm ever going to use CAD in my job anyway, so I mind as well learn it to 3D print shit

any autodesk fusion knowers here? i've got a display cutout in picrel that's fine as-is, but if i'd like to make the housing thicker i'd need to recalculate the depth. is there a good way to define a cut to go up to a certain distance from the opposite face?
can't figure out if i'm doing it wrong but it feels like fusion doesn't play very well with ref dimensions and it kinda seems like maybe an offset plane is my best bet?
>>10130858 months isn't that long or that short but the hell happened?

My company kept me on the bench for 3 weeks, couldn't find a new contract to put me on, then let me go. Took me about a month to find a new job.

I want to create an assembly, not that it mattered rather to gain experience in the assembly workbench.
I'm looking to create the constraints as physically accurate as possible but maybe I'll have to accept some unnatural behaviour of the thing.
The first ring is grounded. I managed to constraint the first ball onto a vertex in the sketch I used for the groove. This is not right but works for now. The next constraint constraints the cage at one of its spherical holes to the ball. More balls can be constrained similarly to the cage. I have no idea how to get another ball to sit in the goove at another point without forcing it. I hope to find a way that will let me undo the unnatural constraint of the first ball to the sketches vertex. I'm okay with constraining to the groove face, groove edge, sketch.
