[...] and in the worst case it could lead to unexpected dangling pointers. Not every programmer is aware of the fact that once a raw pointer is used it must not put into a new shared pointer because then the new shared pointer will destroy it and the original shared pointer will have a dangling poi...

One surface is a plane the other is a spline. Refine will not try to join different types of surfaces.

@tanderson69, I have the physical part here and can upload more photos or measures. Just tell me what you need. I didn't want anything specific. I was looking at the model you uploaded vs my interpretation from your pictures. Knowing you have a physical part, changes the evaluation of those two. aw...

I am still in shock. I can't believe opencascade thickened this!!!! It is very rare that occt surprises me in a good way. That being said, lots of loose tolerances and bopcheck errors, but a thickened solid. I took a different approach to the 'front' this time. I left things square and blended them ...

So I am hoping for ideas for improvement. I have remodeled a lot of sheet metal parts over the years. My approach is to create a big simple solid, like a cube, and start hacking away on it until I get something with 'one side' on it. Then extract the faces that are that 'one side' and thicken*. See...

Nice! :mrgreen: Let me know when it is an external library. Couldn't this be implemented as an addon workbench by taking all of the C++ compute intensive components and compiling them into a binary library and then having the functional integration with freecad through python? ... ... Couldn't this...

Nice! Let me know when it is an external library.

I was referring to things like this post where it appears the occt geometry tolerances are being set by a user through the python console.

Summary: Anything using the shapefix package of occt can trigger the BOPAlgo_InvalidCurveOnSurface error. Yes refine/removesplitter uses shapefix. I did a deep dive on this last year. My advice: Inspect the actual tolerances of the edges that trigger the error and see if they makes sense. Making sen...

Yes, we have to think about this some time in the future. And yes, I think it's probably best to switch again to a scene graph based library like OpenSceneGraph or VulkanSceneGraph instead of vtk, DG or Qt3D. Sorry If I have said this before, Robert Osfield (OSG, VSG lead developer) has said that O...
