[Gmsh] Two overlapping spheres

[Zenker, Dr. Matthias]

Hi Christophe,

since you are working on "real" CAD routines: Do you also plan to implement a possibility to detect and merge duplicated surfaces (including partial overlaps) on CAD level? The "cut and merge faces" does not work in quite some cases...
