Hello, I need to get the projection of the angle formed between two datum axes in Pro/E, on the datum planes that I select. How should that be done? Under Analysis>Measure> Angle, there are three selections that need to be made and I though that the third entity is the plane you would like to get the projection on, but it seems like that doesn't do it. Any suggestions? Thanks so much! Roza
Go to the Definition tab and click on Direction, pick an axis that describes the normal to the plane. Unfortunately, direction doesn't include any way to indicate a plane normal while it could as easily be either direction in the plane (xy, yz, zx). Obviously, it would do you well to have created this axis before hand, or you could possibly interrupt this function to create one 'on the fly' by simply selecting the 'Create Axis' icon at the time you need to choose the directional reference.
