Re: Hardware Recommendations for FreeCAD

Thought I would put this video on hardware requirements for CAD. What can one get away with using consumer cards? Benchmarks included.
Video is from 2018.

FreeCAD challenge and advanced tutorial on surfacing.

I have not attempted the following tutorial from a Solidworks Surfacing guru but thought someone might do something similar with FreeCAD. My experience is to limited with FreeCAD and therefore inefficient or inelegant so i will not attempt it. The link is to a picture of modern sunglasses but not th...

Re: Discussion: FreeCAD is not ready for 1.0

I think after realthunders topological naming stuff gets put in with pre-0.20 then it can be released as 1.0 next year.

BIM Certificate, what does this involve?

What is BIM certification? Is this just hype? What are some recommended colleges to get one? Online classes are a preference. Thanks.

Re: Modern UI Alpha Released

Thank you. Very nice. Looks professional!

One thing i never liked with FreeCAD was the gloomy default colors used. Dark and depressing. All the other CAD packages have a more cheerful but professional default color scheme.

BTW these two models would make terrific FreeCAD splash screens provided proper attribution is given to the inventor.
My thoughts as well.

Re: Reimplementing constraint solver

OH OK.

Anyway, here is some more.

Wolfram Alpha has some widgets for Simpson's rule and others that might help. I have never used them.

Re: Reimplementing constraint solver

@abdullah I know you can use sage. Can you please figure out average value of fourth derivative of sqrt(sq(a*cos(u)) + sq(b*sin(u))) across the period? I'm trying to find out, how many slices should I take for length integration for arc ellipse to achieve a cretain precision, using Simpson's rule ....

Re: Reimplementing constraint solver

There are some requirements: ... I know DeepSonic has been re-implementing things with (dual?) quaternions and i got interested in them with regards to screw-displacement theory. I do not know if that is the direction this could evolve with regards to 3d-constrains in sketches and assemblies. In an...
