Hey all,

I'm involved with some work, where I'm required to rotate the local axes system of solid elements; through the OAPI. Eventhough there's an API function to do this, the angles of rotation are to be specified as angles a, b, c; which are the angles of rotation about Z, Y' and X'' axes.

As I know the angles of rotation with respect to each axis; I'm finding it difficult to convert those angles, into the form of angles a, b, c. I'm sure there's an easy way tackle this. Your help is much much appreciated. Thanks a lot..
