SO GREAT !! Thanks a lot for implementing that. This is really powerful and usable. Some CAD systems provide also the possibility to snap, for example, at the intersections of lines (without having a real point) or in the middle of circle. Usually, the cursor will change depending of the type of snapping. But this is of course more than a nice to have. Thanks again ! Cédric
