I have hard time understanding something...
Bear with me, I´m trying to make myself clear.
I have a part thats looks like this.
The 8H7-holes are clear to me. I can report the positions with A,B C. No problem.
No comes the part that is hard for me to understand, since I don´t know how PC-Dmis solves that.
My alignment is in the left bottom corner.
Then I do the datums D, E.
Then I report the positions of the Ø10 holes.
But here is my problem:
They refer to the datums D and E but the theoretical dimensions refer to B and C.
When I choose "DISPLAY_COORDS=DRF" it basically sets the aligment to A, D, E and reports refered to that alignment.
When I chhoose "DISPLAY_COORDS=CURRENT ALIGNMENT" the reported values are based on the theoretical dimensions shown on the drawing.
The deviation of both positions are the same.
But when I report the Ø10 holes to B and C the deviations are different.
This is the point that I don´t understand how PC-Dmis solves that.
sound like a clocking issue, the angle from "E" and "C" are off. ask for the location to "E" from your ABC alignment thats what your error. calculate what the angle is supposed to be to what its measuring
