Dynamo - DynaShape - Geometry Intersection Points

I did several simple testings on the DynaShape package. The mesh (pull down gravity) is able to stop at the straight line listings. However, it won’t work on the circle listing because the circle’s points do not overlap the mesh intersection points. I am trying to apply the DynaShape’s on more practical situation. For example, placing a layer of ETFE on curved trusses. Does anyone have a solution?
