Summary0003374: Sketch + Gui.SelectionEx() - - - Identify Geometry Index Outside Edit Mode
DescriptionDiscussion Thread in Forum ... (seem more than Sketcher, 'Selection' function?)
"Sketch - Identify Geometry Index (inside and outside Edit Mode)"

Problem is:-
Gui.SelectionEx()[0].SubElementNames would provide different Edges 'name' Inside and Outside Sketch Edit mode ...See screencaptures
  1. Say a rectangle inside sketch, Edges index report are, Anti-Clockwise, 1-2-3-4 [EDIT] ('1' being the edge at the 'bottom')
  3. Edge 2 is construction
  5. Exiting Edit mode, same code seem report the Wire edge number created, INSTEAD of the Geometry inside edit mode
  7. So, only 3 edges form a wire Outside edit mode
  9. Edges nos. BECOME (report here as it is in same direction) 1-(none)-3-2 [EDIT] 3-none-1-2 (same edge by edge)
  11. Or ClockWire as 1-2-3 [EDIT] Top Edge is '1' now
  13. Using the latter 'index' in sketch.geometry[index] would report wrong edge (following Geometry Index) information
So, Solution I haven't found:-
  • Outside Edit Mode, how can I without enter edit mode, a script to identify the selected edge's (the wire shape I guess) internal Edge geometry Index?

Feature Request
to return the same name or index as in sketch.geometry[i]
