       'qdis' RETURN 'w'|'c'|'n'|'p'|'q'

This keyword is used to measure distances between two nodes or points. Move the mouse pointer over one entity and press the following key, for a node n, for a point p or for a centerpoint c. If the key c was pressed then the distance between the two nodes or points are given in cylindrical coordinates. Here lcir is the length of the arc da the angle dr is r2-r1. If no centerpoint was chosen then the distance and its xyz components are given in the cartesian system. But in addition the cylindrical distances around the origin and around the xyz-axis are also given. Press ``q'' to quit the command.

- 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.
