Hi Chuck, type in this in the compass-needles Javascript-window:
//--Script begin //-- Get the actual Rotation rota = Self.GetTotalRotate(); //-- Set x and y rotation to zero and z to actual rotation Self.SetTotalRotate(new r3Vect(0, 0, rota.z)); //--Script end Matthias ----- Original Message ----- From: "Charles R.
