So I have a simple alignment. Plane A, circle B, circle C. I Leveled to the plane A and origin Z to it. Translate XY to circle B. Rotate to a line made from B to C. Done.
A different programmer believes I
mustrotate before translating.... I totally disagree on this simple alignment. Using Legacy btw.
Ran a test... with the Plane, circle, circle I saw no difference. With a Plane. Mid Plane, Mid Plane... Error occurred that was corrected by rotating 1st... I assume its a cosine error of some sort but, it happened and I will change the method for this and future program to form a habit. It actually created .008 inches of error.
This was a case of and old dog showing and old dog new tricks.
