dragging the line on the blue rectangular point. But you also may enter in the
revise window any angle from 0° to 360°.

to size the length of a line exactly. Normally the size is changed on
the screen by dragging the red rectangular point of the line.

Selct from the menue the
color of the line or enter the RGB values (0 to 255).
PenWidth:
Select from the menu one of
the predefined sizes for example 0.5. You may also enter any value by the

It is necessary to use a
point as decimal separator, not a comma!

the lines.
