Rotational offset on Z plane

[rrc1962]

Hmmm...If I rotate the part with X0Y0 it works fine.  If I rotate using a X or Y value to keep the origin at the lower left of the part, I get errors.

If I rotate 90 degrees around X0Y0 the part origin shifts to the lower right.  Is there another offset command I could use after the G58 to correct that?

Have you tried rotating the prgram from the MDI page LH side coord rotation box to see if there is any difference in the error ?

When you rotate the part the 0,0  goes with the rotation so it will rotate the angle as the rotation angle

Just a thought, (;-) TP

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
