10.9.15 Intersection

• Intersection( <plane>, <polyhedron> ) [, facet] )
• Description: the plane must be in the form: $\left[S,u\right]$ (plane passing through the point $S$ and normal to the vector $u$). The macro determine the intersection of the <polyhedron> with that <plane> and returns the result in the form of an edges list (that can be drawn using the macro DrawAretes). It is possible to get the intersection in the form of a <facet> by putting a variable as third parameter.
