Hi Michael,

I guess the use of Multi-core CPUs will benefit Boolean operations,
but i was more thinking about the meshing parameters

For example I draw the parts of the model steam engine which i put
i the Moi gallery
Normally i use a mesh angle of 5 degrees,showing a smooth surface
For the Drive chain i had to set it to 15 because i think the videocard
(Nvidia 7600gt) was suffering

So a more powerfull videocard is on my wishlist
