I want to hit "F" and add an edge between the last vertex of the real object, and the first vertex of it's array-modifier-duplicated clone.
The problem is, selecting the first vertex of the clone actually selects the first vertex of the original instead, so the edge goes in the wrong place.
This is wrong: the new edge should connect the gear teeth together, not close off the tooth.
There doesn't seem to be a way to set the cursor to the cloned vertex either.
What's the fastest way to add an edge (and required vertex) as if the cloned vertex were actually there?
