Hi all, I want to rotate a model by 90 degrees about the axis of symmetry, but I seem to be having problems setting the axis correctly. After two identical models are superimposed I use measure rotation and get the following: Matrix rotation and translation -0.04092271 -0.36724445 0.92922379 -82.20183653 -0.91203666 0.39354649 0.11537022 -54.21831923 -0.40806183 -0.84276490 -0.35104539 11.47082481 Axis -0.55288898 0.77167664 -0.31437070 Axis point -56.22800779 0.00000000 25.47389901 Rotation angle (degrees) 119.94780111 Shift along axis 0.00338820 What should I do to rotate the model at the same axis but by 90 degrees? Many thanks, Liam _________________________________________________________________ View your other email accounts from your Hotmail inbox.
