Is it possible to cut/trim a non-thickened surface?
I know you can through python. I don't if/how you can through the gui.

Re: Fusion Problems

Tanderson did you shorten the U edge by 0.15mm leaving a 0.15mm gap between the U and V ends? Or did you rejoin them but without tang-ency? No. I didn't do any work with curves. I just trimmed the entire bottom of the surface to prove out, that once those u,v tangencies were gone, the thicken will ...

Re: Fusion Problems

Try eliminating the tangency between your u and v edges. I trimmed .15mm off of the bottom to avoid that area. Then I could thicken and get a valid solid. You can still see a wrinkle though.

Re: checkgeometry->bopcheck in background thread

The BOP prefix stands for B oolean Op erations and is only supposed to be used for the result of boolean operations. Norm said the same thing and I think this statement is misleading. When a boolean operation fails they use it on the INPUTS to the failed boolean operation. Think, "boolean simulator...

Re: checkgeometry->bopcheck in background thread

I'd really like to see progress indicators with cancel options used more in freecad The problem with OCCT is that there are only a few algorithms where a progress indicator can be set. BopAlgo_Options will take a progress indicator and the BopAlgo_ArgumentAnalyzer is a subclass. So it looks like th...

Re: checkgeometry->bopcheck in background thread

Thanks for the feedback. I'm not sure I understand those numbers, but the This is great! part, I assume, means you got better performance with it enabled. from 443 seconds down to 151 secoonds. :D You suggest removing the line BOPCheck.SetParallelMode(true)? Any harm in leaving it as is? What is th...

Re: checkgeometry->bopcheck in background thread

I removed the multi-threading stuff and just added the runparallel mode option. It looks like a background thread option for runbopcheck is going to be a no-go anyway, at least for the time being. The 'BOPCheck.SetParallelMode(true)' call is not needed. That was me probably in a desperate act to sp...

Re: Shape sharing and save-restore

Did an experiment this morning. If you look at the code for 'BRepTools::Write' it isn't really doing anything other using BRepTools::ShapeSet https://git.dev.opencascade.org/gitweb/?p=occt.git;a=blob;f=src/BRepTools/BRepTools.cxx;h=7572bdc0e82e95562413bd032f3c670f9f1adb1c;hb=HEAD#l689 BRepTools::Sha...

Re: Merging of my Link branch

This is because PropertyTopoShape performs a copy before saving, which seems to be a deep copy and destroys the shape sharing. I have just submitted a PR In regards to the pull request: The link you posted is for writing binary tools. Doesn't FreeCAD saves in the ascii format? Seems like 'BRepTools...
