Since I was using positional tolerances for a lot of features I wanted to use ordinate dimensions to make the drawing less cumbersome.
But I have noticed that values the ordinate dimensions are not showing correct all the time. When the ordinate dimension is off of a center mark it is incorrect many time but not always.If the ordinate dimensions is off of the feature then it looks to be correct all the time. I have tried deleting and recreated the center marks and views and that most of the times but not all the time.
I have figured out that dimensions are off by the cosine of the angle the surface is off from one x, y or z plans. All my views are normal to the surface that I dimensioning.
The attached images of showing the issue. Regular dimensions are always correct.
Anyone have a clue as to what is causing this? Is it a feature I am not aware of (I can't imagine it is as there is no indication that the dimension is not what it looks like)?
This only became apparent to me when I dimensioned feature that are symmetric and they were not showing up the same. One dimension was showing .24" and the other was .09".
