I copied your code and got this mesh out of it:

Which PMC method are you using?

Works in Analysis Situs: In should actually be handled by OpenCascade itself, because its translators accept `const char *` for the input filenames assuming that the filename might be represented with UTF-8 encoding. When OpenCascade opens the input stream, the string is converted to unicode...

Analysis Situs employs Qt as the user interface framework but we never used Qt Designer to put it together. All layouts and controls were programmed right in C++, without any wysiwyg editors.

This one is a commercial software package, so I do not have a reusable piece of code to share. The idea is pretty straightforward though: you load your file to another XDE document and then copy the roots from this second document to the first one. You will also have to transfer all labels with...

Interesting. Our take on rough milling volume estimation was/is based on feature recognition. We first identify all prismatic features (not to mention holes as they are easy to process), and then try to construct their corresponding negative volumes by extruding those features' outlines towards...

I'm curious how far have you managed to get with this BOP-based approach. Never tried to implement something like this myself but I heard that other people used some other shape representation techniques, such as dexels, voxels, ad-hoc wireframes to give such an algorithm a somewhat better FPS...

To be honest, I have never used XLinkTool. But it kinda makes perfect sense that you link one self-consistent document to another, and not refer to any individual components (sublabels, etc). As a side note, what also makes a lot of sense is to invest a bit of time in understanding the internal...

Is this material removal simulation? How good is it with OpenCascade's Booleans? I bet it shouldn't be super fast :) You can try ShapeUpgrade_UnifySameDomain for removing imprinted edges and this way maximize analytical faces in the shape.

Implementation in C++ for reference: https://gitlab.com/ssv/AnalysisSitus/-/blob/master/src/asiAlgo/re/asiAlgo_PlateOnEdges.h

Have you tried GeomPlate algorithm? It is the GeomPlate_BuildPlateSurface class. It looks a little bit smoother in the result.

Can you attach the brep file for the face you got with constrained filling?

All what is written above is temporarily pushed to a branch https://gitlab.com/ssv/AnalysisSitus/-/tree/min-Z-surf-opt Search for MISC_Test C++ function.

If your optimization is done in the UV space of a surface, then I do not quite get why would you need point projection. It looks like a two-dimensional problem where your objective function F = Min_Z( S(u,v) ) is defined by two unknowns: u and v. I quickly tried the following scheme: Apply PSO...

Those seam edges are the essential part of a face representation in OpenCascade. For any periodic surfaces, they go through the period value to close the parametric UV domain of a surface (otherwise it would remain unclosed). What you probably want to ask is how to get rid of those edges...
