Project a 3D point from MouseMove to x-y plane?



I am stuck at this: I would like to know in the MouseMove event with the model coordinates dX, dY and dZ where this point is located in the x-y plane of my assembly. If I just set the z coordinate to zero then in iso view the point is located upwards or downwards from the mouse position. I think I have to project the 3D point to the x-y plane using solid egde camera parameters. But I dont know how and the documentation on the camera parameters (eye, target and up) is very sparse.


Anyone with some useful tips?
