'qali' RETURN 'w'|'p'|'n'|'q'This keyword is used to align a plane defined by three points or nodes with the screen (working plane). This is useful if a point or a node should be moved manually along a defined plane (see qpnt). To define the plane move the mouse pointer over the first entity and press ``n'' if its a node or a ``p'' if its a point. Then define the next two entities in the same way. Press ``q'' to quit the command.
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.
