Re: Sketcher: Bezier curves

Thinking a bit further. A clone of a geometry is an independent copy, i.e. it doesn't share the underlying OCC geometry with the original. But a clone will get the same tag id as the original and I am not sure if this will lead to problems in the future. In the context of the sketcher, a clone is e...

Re: Sketcher: Bezier curves

Note: I have managed to segfault FC by fully removing one knot (ask to decrease multiplicity when multiplicity was 1). This is a bug to correct. I have not been able to make it complain in my tests. This might be the same issue I encountered but on Windows it doesn't segfault due to compiler settin...

Re: Using PlaneGCS as the sketch constraint solver in SALOME

Regarding the cases I have reported in my previous message. It is very strange for me that similar cases has different result. Indeed the result depends on the solver. I will try to investigate this problem at leisure. Thank you one again! You are welcome!! I think DeepSOIC is absolutely right. Fro...

Re: Sketcher: Bezier curves

point selection is not cleared I took the decision not to clear the selection when executing the commands (so that you can continue changing multiplicity of the same knot). For increasing after increasing, it seems to be a good idea, but when it involves decreasing I have realised it does not work ...

Re: Sketcher: Bezier curves

It would be good for real errors to raise an exception and let the calling instance (here the command) handle it. At the moment when returning false it sometimes means that the function fails due to wrong input parameters and sometimes to due a real problem. So, the calling instance cannot distingu...

Re: Sketcher: Bezier curves

3. Review return types in functions (I have some boolean returning functions that should probably better off by returning nothing and raising an exception if something happens) I would appreciate a word of advice from somebody that understands how python commands, UI commands and DocumentObject met...

Re: Sketcher: Bezier curves

No problem! Thank you for your understanding. After a lot of trials (all failures so far) to try to reproduce this issue outside FreeCAD, I have realised that it only happens (so far) in bsplines with 5 poles and 1 knot, and not in all of them. As it is not crashing FC (the exception is ultimately ...

Re: KiCad and FreeCAD collaboration!

Hi Maurice! I am really happy that these communities are today a little bit closer than 1 year ago. I also think there is a lot of potential in connecting the two. BTW, the components look absolutely amazing. You should also check out my repo at https://github.com/realthunder/fcad_pcb. The original ...
