text: I’m trying to automate an external CAM plugin I have through Grasshopper. Each operation I’m trying to automate requires me to input a surface, a surface edge, and a curve from the main Rhino doc. (I have potentially hundreds or thousands of surfaces work through in a given file which is why I want to automate).
  I have generated pairs of matching named surfaces and closed curves on a named layer. The script grabs the the pair of GUIDs and names for the matching surfaces and curves. (For example data looks like:
  [(('000_dsurfaces_srf', '312664e8-7a71-465a-ab99-0d17a72d1eb4'), ('000_dsurfaces_crv', '36064a53-ff8f-4e1d-90cf-133a2ec6275e')), (('001_dsurfaces_srf', '581d9b2b-4b4a-45f2-a8cd-3e8fd97c30d1'), ('001_dsurfaces_crv', '35468a3c-6e46-4fa1-acdf-0a4b52a2f04e'))]
  What I need to do is:
  - select a surface
  - hit Enter
  - select any one of the surface edges from the above surface
  - hit enter
  - select a curve
  - hit enter twice.
  I have GUIDs and Object names of the surfaces and curves I need, but I can’t figure out how to select one of the surface’s edges. Is it possible?
  (Currently the plugin only works in Rhino 5, but I have both Rhino 5 & 6).
