Angle Results from 2 Auto Lines

TESA/PC-DMIS CAD 4.2 MR1 RELEASE

Using Auto Line for 2 separate edges (2 points selected for length and location of line), Test button each time, Create button each time. Back light is set to 50.6. Close button.

Select Angle Dimension, Last Two button, tol. +4/-4, nominal = 90 deg., Create button.

10 results (in degrees):

87.4, 92.6, 92.7, 92.7, 87.5, 92.6, 92.8, 87.3, 87.4, 92.7

*note: I never moved the part. I just repated the process listed above. The results were gathered within 3-5 minutes total.

No pattern seen. This is the results for the same part, which was never moved.

The angles seem to be complimentary angles because you get relatively close to 180 degrees when you add a low number and a high number or when you add the averages of the lows and the highs.

What may be going on here?
Which results might I record for my D.O.E.?
Would you take all of the small angles or all of the large anlges for your results?

Help.

Sorry, it took me so long. That feature is set as relative to feature. I have yet to see it change by itself. I'll keep looking for that though.

Here is the code you requested a while back.
