Hi Amir,

As full planes are valid Nef polyhedra, you can apply the join operation
on them in order to obtain their arrangement.

Concerning the planar patches the main difficulty will be to generate them.
If they are given as a polygon with floating point coordinates on a plane
chances are high that the precondition fails that the points must be coplanar.

best regards,
