Hi Michael,

I also think it could disable all of them, straight, grid and object snap.

"If so, could you show an example of one? I've generally tried to make it work well to keep all the different modes active all the time. If you're running into problems with that, if I could see the situation it might help me figure out how to improve things."

Yes it is true that snapping work very well in most conditions. A situation I can think about is when you want to snap to an endpoint of a line and the object is inside a complex solid. It is sometimes not so easy to distinguish between the edges of objects and the edge that are inside, this could somewhat facilitate the selection.

Regards,

Marc
