qsur


   'qsur' RETURN 'w'|'a'|'i'|'r'|'1'-'9'|'g'|'q'|'u'
This keyword is used to create a surface (see also gsur). For this purpose the three to five edges of the surface must be defined. To create a surface move the mouse pointer over the first line of the first edge and select it with the ``1'' key. If more than one line is necessary to define the first edge select the following ones one after the other with the ``1'' key. Each marked line is listed in the mother xterm. If all lines of the first edge are selected select the lines of the second edge by pressing the ``2'' key, than the third and eventually the fourth and fifth. The last selected line must match the first. All lines defining an edge will create a combined line (see lcmb) and this combined line will show up in the definition of the surface. Then generate the surface by pressing the ``g'' key and you might continue with the next surface. To quit the command use the ``q'' key or use ``u'' to undo the last action.

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.
