Creates a 3D object between two 2D objects that lie on different planes. The planes do not have to be parallel.

1. If you want to select only simple (single-object) curves, make sure Use Compound Profile is not selected. 
   
2. Select the two 2D objects.

   Prism with Compound Profiles
   A compound profile is an open or closed chain of connected curves or lines. You can use compound profiles when you do not want to create a polyline, or convert a chain into a polyline.
