Press ``q'' to quit the command. After you selected two entities you will get information about the distance and the angle between them relative to the origin and to the x, y, z-axis.

- dist: global distance
- dx, dy,dz: distance in the three cartesian directions
- da: global angle
- dax, day, daz: angle around x, y, z
- dr: global radius difference
- drx, dry, drz: radius difference around x, y, z

It is also possible to measure distances between two pixels on the screen. Just press the key ``w'' on the positions of the two pixels. The distance is calculated in the scale of the displayed geometry.
