PC-DMIS 2021.2 - Possible bug with variable of position evaluation

Aaron Baldauf
Hello

I think I found a bug with the extraction (in a variable) of the z value in a position command.

I have a position of a plane to datum B (also a plane). The nominal distance is 43.64mm.
The measured TP value of the feature is 0.518015 and the measured z-value of the feature is 43.899007.

When extracting the z-value via a variable I get a totally different value of ​43.810238. A difference of approx. 0.09mm

To verify the result of the position feature, I aligned to datum B and evaluated each z-value of the plane.
The worst z-value of the individual points is 43.899024... so nearly identical to the position evaluation.
So the error must be in the extracted value.

I don't have any special characters in the name of the features.
PC-DMIS version is 2021.2 SP8 (Build-Nr. 524).

May I send the routine to one of you guys to investigate?

    I'm aware that the extreme point is part of the newer version of PC-DMIS.

    I meant that it would be great, to have a similar tool (like the HighPoint.exe before PC-DMIS got the native ability) but to help the user extract axis data.
    The current way of extracting the axis data is way too complicated for the user. The old syntax still gets accepted by PC-DMIS but can give wrong results.
    So a tool like this would be a great benefit. Of course a native solution would be preferred.

    I'm in contact with David (and Don) from your team and he mentioned he will talk to you after both your holidays.
