Purpose
Usage
Click the offset button to activate it. Click on the curve of which you want to
offset a copy. By holding the middle mouse button pressed while moving the
mouse, the distance of the offset copy to the original curve will change. If
the keyboard button is active, you must enter numerical values.
Comments
The offset of the original is an approximation only; the offset of sharp curves
will not be correct. The approximation will be better if more points are added
in the problem regions.
