I'm working with an imported shape file that has lots, and I'm trying to use setback() with it. I've done some analysis and I've got a list of all the street facing edges for each lot, but there doesn't seem like a good way to feed that information back into the system (there doesn't seem to be a good way to set an array attribute like streetWidth).
Any thoughts on the right way to do this? There doesn't seem to be a clear way to "manually" do the operation myself (not all the lots are quads, so comp(e) with variable length indices doesn't seem possible)
So it can be that then, the streetWidth() attributes with the value '0' do not appear in the Obj Attr list in the Inspector, which even may be better. Try playing with this.
Concerning the indexing : Note that ArcGIS stores the vertex order clockwise, while CE interprets the vertex order counterclockwise, which messes up the order you have in ArcGIS. But you can fix this by a function which translates between the two worlds.
