Re: An idea how to solve cross-cs support and assembly recompute

What import action are you referring to? import asm3 This import is used frequently in your code. But you didn't provide the asm3 module in your GitHub repository: https://github.com/realthunder/FreeCAD_assembly3 Hmm...that's strange. How can you get anything work then? The reason for that is, my p...

Re: An idea how to solve cross-cs support and assembly recompute

@realthunder Imports (asm3) are broken/missing ATM. I did get to the part where i could insert new Assembly and add a few parts to it. By fixing the imports. P.S. Didn't manage to get to the Constraints/Solver situation today. What import action are you referring to? I've added some import commands...

Re: An idea how to solve cross-cs support and assembly recompute

I plan to doodle some assembly graphs, stay tuned. It's going to be even more pictures, so it's going to take a while. It's been a while since my last post regarding anything about assembly. It is because I actually started working on assembly3, about three days before you started this thread. My a...

Re: Facing Operation?

There is something wrong with the projection wire joining algorithm. I'll try to fix it soon.

Re: Contour Path positioning error

Given that it affects one out of four 90º corners, and only on the exit I have a hard time classifying this anything other than a bug ;) I did some further investigation. Here is the actual cause of the problem. libarea feeds ClipperLib with four simple straight lines of the Cube, while ClipperLib ...

Re: Contour Path positioning error

Oh, I forgot to mention this. When doing arc fitting, libarea doesn't really know in advance whether the line does belong to the arc or not, So it uses some heuristics with some tunable parameters. Now, what if the user actually intend for some small line to be actual straight line? And that's what ...

Re: Contour Path positioning error

Given that it affects one out of four 90º corners, and only on the exit I have a hard time classifying this anything other than a bug ;) This is because the contour is continuous. The problematic stray line is either at the beginning or at the end (which may not be so in the gcode, because the path...
