Is there a way to report the (u,v) location on a surface? I'd like to tell a pattern-based component to adjust based on its position on the surface. Here's a simple example: Given a rectangular pattern, change the height of a rectangular panel as U and V increase. Any thoughts? I'd like to do it in Revit, but if I can't, I'll have to resort to a script in Rhino or Grasshopper.
