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.
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.
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.
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.
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.
