Plotting issue in TIGL Viewer after rotation of rotor

[YaCabac]

Hi,

when I am plotting my rotor in the TIGL Viewer (without any rotation applied) I am getting it in the default orientation as described in the CPACS Documentation. Additionally, to the rotor blades there is special circular rotor grid connecting all the blades' origins (see following fig). So far so good...

However, as soon as I am applying a rotation to the y-axis by 90deg (xPath: /cpacs/vehicles/rotorcraft/model/rotors/rotor/transformation/rotation/y) I am getting the blades in the new expected orientation but the special rotor grid is shown the other way around (see following fig). This issue only occurs when rotating around the y-axis for values of exactly +-90deg and +-270deg.

Is this maybe a plotting/displaying bug? I am looking forward to get some support for this issue! I also attached a small example file for testing (it is a .txt since .xml is not supported -> just change back to .xml).

Kind Regards,
Yannic
