The above commit enables copying of external geometry. There is some limitation at the moment. It is due to the fact that there is no constraints on the external geometries or between them. Say you copy a set of connected external edges, there is no coincident constraint between them, so you'll have to connect them manually. There is also complication if you copy geometry that constrains to an external geometry. Because it is not obvious visually which external geometry are constrained against. See below for example. The geometry is connected to the arrow pointed external edge, but not the other one. If you copy the edge together with the wrong external edge, the copies won't be connected. This problem exists for normal geometry copying as well, but it will be more obvious when external geometry is involved, since there is no constraints between them in the first place.
