Confirmed.
Filling and Gordon works but not "fill boundary curves". Probably not because the edges but the feature.
Surface_GeomFillSurface

However, I get a report: Surface filling: Curves are disjoint.

Another notable observation (which doesn't fix this issue, sadly): the Add/Remove buttons in the task view do not visibly toggle, when the add/remove logic is clearly designed around the modal behavior similar to PD dressups and FEM constraints.

Sorry for the grainy quality. Still haven't found a way to screencast properly.

On my Windows builds I get no crash if I build in debug mode, but can reproduce if I build in release mode. The actual crash is occurring in OCCT's TKG3d.dll, but I don't have debugging symbols build for it so I can't see exactly what's going on.

The TKG3d.dll appears to exist only until OCCT 7.6.*: https://dev.opencascade.org/doc/occt-7. ... tkg3d.html. I couldn't find the package in the documentation for 7.7.0 and above (or maybe just the documentation hasn't been transfered?).
