Dear Community,  
since hours I try to figure out, how to align all CoGo-Lables to the selected 3D-Polyline.  
My code includes the selection of CoGO-Group and the polyline object, creation of vectors and angles in cogo points.  
I would like to alingn the lables with the lines, o which they are located.  
Somehow I get always a wrong list of vectors.  
Please help.
