Maybe this didn't come through quite right: I'm not interested in the intersection surface at all; all I want to do is carve cavities out of an existing block of "material". Suppose I have a cube with edge length 10 centered around the origin, and I want to carve out two ball cavities with each radius 1.5 centered at (1,0,0) and (-1,0,0), respectively, then gmsh would already bail out.
And by the way, what would you say is a good "solid modeler"? --Nico On Sep 6, 2012 10:39 AM, "David Colignon" <[email protected]> wrote: > Hi Nico, > > Gmsh is not a solid modeler and cannot automatically compute the > intersection between surfaces and/or volumes.
