Selection.add ??? possible?

[artmusicstudio]

hi,
when i have

model = Sketchup.active_model
sel = model.selection

and create a edge-copy from a given edge (from an edge-array : edges)

entities2 = Sketchup.active_model.entities
vertex = edges[0].start
pt_start = vertex.position
			
vertex = edges[0].end
pt_end = vertex.position
					
edge2 = entities2.add_line(pt_start, pt_end)

how could i ADD the new edge2 to the sel ??? (merge ?)
is it possible?

after this the further code should realise sel incl. the new adge2 as USER's SELECTION .

thanx
stan

I don't think Sketchup will allow you to place one edge on top another in the same context. The copy would have to be created in a group then sel.add edge2 would add it to the selection.

[TIG]

sel.add(edge2)

BUT best to test it's valid - edge2.valid?

BUT beware!

The entity must be in the model.active_entities context...
You can 'cross-thread' selected entities BUT it will crash SketchUp...

Was that a question on how? Or did you experience issues with Selection.add (because that is exactly the API method to do what you requested: http://www.sketchup.com/intl/en/developer/docs/ourdoc/selection#add )
