Rotation Problems

I am drawing a 3D bent tube in space, and I need to be able to rotate and move the part ALWAYS relative to a WCS. glTranslate & glRotate are always relative to the part it seems. I want to have Move and Rotate commands which will always move the object on axes parallel (perpendicular in the case of Z axis) to the user’s point of view, regardless of the part’s orientation. How can I do this?

The red book have a good section about the coordinate systems.
Your other question is it about billboarding?
