Saving the Rotation Angle of Cells within DGN file

Hi,

when I import a MicroStation dgn file in GM (v21.0) cells were imported as point features. Some cells have got rotation angles in MicroStation.
In order to draw symbols with GM correctly, I have to read out the rotation angle value for each cell.

How can I do this with GM script? I searched the GM Help but can't find any information. I hoped that the rotation angle of cells is read by GM like style attributes (e.g. color, line stile, ...)

best regards
Daniel
