split face Curvature comb edge select problem

[cekuhnen]

one edge refuses to be selected - edges are created via the split edge command based on a cplane

I believe I know what is going on here! If you look at the edges that are not selectable, you'll note that they are linear edges with no curvature. Curvature Comb is restricted for linear edges. 

I hope that helps. Let me know if there are questions/concerns.

Cheers,
