OK I rotated serveal other test files and finally got one to error on an arc when rotated with a G68 call with an OFF 0,0 rotation point.
SO there IS a problem here with arcs and G68 call . Not all arcs fail and never from a 0,0 rotation point. The arc that failed was a G3.It also never failed from teh Rotation window on the MDI screen.
THanks for the extra testing, (;-) TP
