_33 Darkbasic Pro has had CSG for a while but it's slow and very buggy (so it fits in weel for DBP). IMHO it's very difficult to do realtime CSG particularly with enough flexibility to be useful. Hell even big professional 3D modelling packages still have some issues with CSG and it's not quick. Exepecting Blitz to do this...well you might as well ask for the rest of the features in my previous ironic post.
