Hi All.
When using _InsertEdge from the SubD-toolbar in Rhino 7 WIP:
If no edge is preselected when issuing the command, you are good to go, but if an edge is already preselected, you’ll end up with the _Ring/_Loop answer, which are not valid options at that time.
I guess it could work for now, but it should be fixed in the final release of 7.0.
