I thought I would knock some dust off my drafting skills after a small chat with @captain_aggravated@sh.itjust.works
Seeing this image on the tutorial made me realize, FreeCAD seems to be a Technical Geometry Super-Suite. It makes sense that CAD would grow to include all of these things. But I thought sharing the initial perspective of some one who hasn’t looked at this stuff in about 18 years might be interesting.
Granted I’m not actually familiar with most of this stuff, and none of it from the POV of FreeCAD. If this can deliver 10% of what I’m looking at, I’m in for a treat.
Seems like a good opportunity to ask if anyone can recommend learning materials for FreeCAD? Used Solidworks and AutoCAD in school but fell back on tinkercad for a recent project just cause I didn’t have time to invest in learning.
This is a pretty good tutorial to get started in FreeCAD. Just watch out for the topological naming issue. They still haven’t fixed it, but if you know how to avoid it, you shouldn’t have too much trouble.
That is an insane bug to have in your CAD software, I don’t see how it’s usable for any slightly complex part.
Literally every CAD program suffers this to a greater or lesser degree. There are workarounds but they’re clunky.
Here is an alternative Piped link(s):

Parametric is such a leap, when coming from toy blocks like TinkerCad in which I can really easily do all that I want except those sexy fillets…
I really want to learn it but it feels so convoluted and difficult. I’m aware that FreeCAD is not the easiest, and some commercial packages are easier to grok but their licensing is really hostile to simple hobbyists so I am trying to to take the high road, for now anyway.
If you don’t want to make parametric models, you can build simpler things by combining primitive shapes in the FreeCAD part workbench. You can even fillet and chamfer them.
Hey, I have used freecad a lot. FreeCAD is good, not great as a cad software. But it is the only truly “no strings attached.” The problem with it was development was almost at a standstill for things that actually mattered. A new company has formed around commercializing it and are working with the original Dev team.
Updated UI, topological naming fix, some assembly and actual functional defaults were promised for Q1 2024 and releasing it as a 1.0 version.
I think it is worth it to learn how to use right now as in the next 2 years it should become an actual viable CAD alternative for things outside of simple projects.
I wouldn’t try parametric models in freecad. They use a really really bad spreadsheet reference system that recalculates you model, not on every change, but every CLICK which means that when you have a variable that is reference more than 10 times or so, it begins to take longer and longer to even start to enter a new value. One time it took 5+ minutes just to get into the spreadsheet cell before even being able to edit its contents.
For parametric, use OpenSCAD (or openscad in freecad) until they implement actual, working variables.
I often read that the UI is pretty unintuitive compared to the commercial competitors. I anyhow started with FreeCAD three years ago and never looked back. I design a lot of functional 3D prints with it and managed to solve all the issues I’ve faced so far. As I started with FreeCAD and never tried the alternatives, I also don’t miss the possibly more intuitive UIs 😁
I tried qcad around 2010 or so and found the UI horrible compared to autocad that I was used to. At this point in my life, drafting was pretty useless. So I had no reason to have cad unless it was free.
I found OpenScad in Y2020 and was amazed at how far it had come. It felt much more like the commercial stuff, at least to me, who was behind the times anyway.
QCad still sucks compared to AutoCAD, but it is only around $50 for a license where AutoCAD is pretty much subscription only at this point I believe.
We actually use it at work, because our 2d drafting use cases are very limited, but we still need something DWG compatible.
From my perspective the biggest thing wrong with FreeCAD is that it’s a single threaded app in a multicore world. If you load large stuff, the app freezes and one core is working really hard for a while.
Isn’t like every CAD program single core? People got scammed hard with Xeon in the past. CAD PC salesmen had/have absolutely no idea what they were talking about
Biggest speedup has been the GPU integration. The single core stuff doesn’t seem to matter much anymore.
Needs a better logo as well
Actually that’s a great place for some “I want to help but I don’t know computers” people to jump in.
Yep, there’s a ton of great Foss projects that have a shitty logo. Look at Octave, looks like something 10yo me made in MS paint in 5 min
FreeCAD is fairly good. Some of the controls are a bit wonky, but that is just a minor gripe. If you are starting on FreeCAD, that doesn’t matter so much. FreeCAD is good to know if you design components for KiCAD as well.
Parametric modeling is fucking awesome, btw. I am not quite sure how old that concept is though.
All 3D modeling software has absolutely terrible controls. I’m not sure there’s a right way to do it through a 2D interface.
I have seen people use pens and tablets for sculpting in Blender so that is an option. For my CAD work I do have a SpaceMouse but that is only really useful for large projects.
Until we get holographic projection (Iron Man style) I am not quite sure what a 3D system would look like, TBH.
