About Osnaps: I have the most common ones (End, Mid, Perpendicular, etc.) set to On permanently, and the ones I use occasionally or the ones that tend to disturb the drawing process most of the time (in particular Centre) combined in a custom palette that pops up at the mouse cursor when I hit S (= the alias to invoke the macro _ShowToolPalette _ToolPalette=MaxzSnap _UnderCursor=YES _Enter ( default alias for S is '_Snap))
Max.
