Is there any difference in the way Grasshopper deals with Referenced
Geometry vs. Volatile Data (aside from the fact that one has
persistent data and the other is not). The reason I ask if that I
have 2 closed polylines that overlap each other, and I'm trying to get
the inside polyline... almost like a Curve Difference instead of a
Curve Union. So, I've created a simple definition that creates a
planar srf out of both polylines and then using the Solid Union it
creates an object with a set of different faces. Using a little math
you can eliminate all of the smaller faces so that your left with the
one big face in the middle which is just like creating a Curve
Difference (I think). Anyway, the code seems to work when I select
each curve from Rhino using referenced geometry. However, if I feed
those same curves into the curve data using volatile data, the Solid
Union fails which throws off the rest of the definition. So, my
question is, why would it work with referenced geometry but not with
volatile data?
I guess I can always bake the curves into my scene and then re-assign
them back into my definition but it seems like I'm having to go around
my butt to get to by elbow.
Thoughts?
