Problem
I've a structural model with beam elements. I have to rotate the structural model with the GiD function Move -> Rotate . After that there was an error "LOCAL_AXIS_1 is not perpendicular to LOCAL_AXIS_2".

Workaround
In GiD -> Parts -> Beam deleting the assigned Group. And reassign the groups to beam element. A popup informs about updated LOCAL_AXIS. It works again.

Question
It seems like the LOCAL_AXIS are defined when assigning the group to a element. For bigger models this workaround is quite complex.
Is this the way it is supposed to be ? Or is there a simpler workaround ?
Would it be possible to set the LOCAL_AXIS only when writing the mdpa file ?

I already discussed with @mpentek and @KlausBSautter.

The current workflow seems a bit counterintuitive and error-prone (when for example a rotation of a model is done).
