The used CAD-Program uses the SAT-Format of the ACIS-Kernel for 
modelling. It is a volume-based Kernel working a little like Povray CSG 
does. So the bad export is astonishing for me. Perhaps the problem lies 
in the STL-Data with too much numbers after the point, i will check that 
out. But i don't have the CAD-program working now, i need to borrow the 
dongle to use the newest version. There are parameters that affect the 
output of triangles.
