It is important to know not only the distance between the two points but also the angle of the pipe with respect to the coordinate axes during creating and modifying a model. I would like you to add another item to the Tools menu called Angle Measurement or to extend the existing Measure Distance menu with angle measurement. This extension could be optional, the angle between the pipe axis and the coordinate axes would be calculated after filling in the check mark. Therefore, three new items (the angle alpha, beta and gamma) would be added to the existing three items (dx, dy, dz) in the result window.
