Hello !
Hope someone can help me with the following (simple?!) problem:

Imagine a cone being clipped by a plane under a specific angle.
The resulting (clipped) cone is always open (hollow).
How can I avoid this ?

Thank-you in advance.

Jens

Use an intersection rather than clipping it. By using an intersection
the plane will add its surface to the cone object instead of leaving
it open as you are experiencing.

Aargh! I thought we were done with conic sections! ;)
