Hi everyone,Here is a somewhat accurate 3D surface I created by importing a TIN (triangulated irregular network) from GIS, and adding an image as texture.However, I am having trouble draping layers onto the TIN surface as you can see:Anybody know how to do drape these layers on the surface, as well as know how to draw on the surface?I can share the TIN.Thanks!Francescafrancia [at] berkeley [dot] edu
