Individual points: WUWT?

If you get an Edge that’s connected in an open loop w/other Edges, and you select the two end Points, you can Duplicate them and get two free-floating points.

But an individual Edge, when the points are Selected in Point Mode, then Duplicated, gives you a new Edge, not two free floating points. -WUWT??

I’m not sure what you mean. If I’m understanding your question correctly, duplicating two vertices with an edge between them will include the edge in the selection because you are selecting all the components of the edge. Likewise, if you select all four vertices that make up a face and duplicate it will duplicate the face as well, even if you are in vertex select mode.

Meh. Seems high-handed to me.
