My best guess about the Close Hole issue is that geometry Joseph is working there. You xlose part of what. The close convex curvature feature issue if I make the not a slight oval. Horizontal motion gives me no result at all and i at the limit in either.
Folders featuring Joseph Drust. Edge Insert. Gizmo 3D featuring Joseph Drust. I can offer no explanation for the latter issue. So, after a lot of experimentation I believe the erroneous behavior actually occurs when all angles between line segments along the edge of the hole you are trying to close are below a certain angle threshold.
