Hi all!


Please Help me. This mail is 3 times.


I have some problem.
I'm trying to manupulate a 3d object picked by mouse like a manupulator 
in Inventor.
The problem is that the 2D mouse position doesn't translate to a single 
point in 3D space.
I tried to use a trackball manipulator(xformer) to the object's DCS 
matrix but position of 3d object is not matching with position of mouse.


Your answer would be greatly appreciated.


Regards,


KIM.
