I think I found two bugs with the graphical evaluation of the geometric tolerance command:
1 - deviation lines not drawn in the correct orientation
When evaluating parallelism or perpendicularity the deviation lines are not parallel or perpendicular to the datum.
The tolerance borders are drawn correctly though. When evaluating the same with legacy the lines are in the correct orientation.
The measured results between legacy and the geometric tolerance command corelate mostly.
The difference varies from 0.000µm to 0.285µm. I guess the difference here is because the geometric tolerance command filters the datum and measured feature?
I noticed this error in two independent programs. But I also have programs where it works as expected.
2 – deviation lines are red (OOT) but the feature is in tolerance
When evaluating flatness some deviation lines are red but the result is in tolerance.
In legacy all the lines are green.
The measured results between legacy and the geometric tolerance command corelate.
Both measure 0.008502mm. The tolerance is 0.01mm.
I noticed this error in one program so far.
Both errors happen in the same program and I can send it if necessary.
It’s a mm program and I use the ISO evaluation. I use LSQ calculation in the geometric tolerance command.
I measured the part with 2021.1 SP2 and opened it also on our offline station with 2021.1 SP5.
The graphical analysis stays the same.

Can I send this program to one of you guys?
Maybe there is something wrong programming wise?
