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.

I 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.

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.
>>994667
In 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.

>coarse mesh fails the study more often than not
Not 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 slipping
Conctact 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.

For 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-contact
Ah 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 coefficients
The 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.

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.

Just 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.

All 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.

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.

You 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.

Do 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.

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.

I'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.

You 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.

Good 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 heart
Fuck off nigger no you don't.

What 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.

Not 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.

3D 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.

Final 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.

Are 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.

Will 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.
Phonefagging so formatting and speling may be a bit wonky.

I'm feeling like this too.
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.
>>1004819
i need to know what to do please. I want a one button hotkey like R to rotate not R-O-space then click a base point to start rotating.
turbocad for being really cheap did so much better of a job at this.
R45 and it's done. change the base point with D if you need to. man I miss that little cheapo software. it sucked at a lot of things though too.

SW' 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.

Thanks 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.

Any 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.

Perfectly 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.

How 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 90° wasn't specified in the drawing.
I see some extra faces on yours by the corner so I was just curious
Anonymous at Fri, 7 Feb 2025 02:46:37 UTC No. 1007039
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 ?

Yeah, 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.
>>1005638
Thanks 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.
