If to a file, you can later apply the transformation(s) by reading the file with the "matrixset" command (same man page as above). Best, Elaine ----- Elaine C.

I have a 3D object that I have to rotate in order to see certain features. I'd like to know those angles. Is there is a way to get this info?
