CGAL users discussion list

I'm looking for a replacement for the gts tools (GNU Triangulated Surface 
Library) for taking two 3d objects and creating new 3d objects combining 
them, finding their intercept shape, and finding the shape that's inside 
one object but not inside the other object.

first question is if cgal can be used for this? I see some reference to 
finding the intercept shape between two objects, but nothing for creating 
the hape that's the part of one object that's outside the other object.

second question is if there is any sample code that does this?

since my object files are in the gts format it would be ideal to find 
something that understands these file formats, but if not I can probably 
deal with it.
