Description

This macro cut a circle(s) or arc(s) in multiple arcs, the arcs can be coloured alternately to distinguish.

CutCircle

Usage

  • Copy the macro cutCirle in the Python console,
  • Enter (the code is now in memory),
  • Select the circle(s) and (or) arc(s),
  • Then, for example, write cutCircle(5, 1), this command will cut the circle (or arc) and create 5 arcs, colored alternately in red and white as shown in the photo.
  • Or an other example, write cutCircle(4), this command will cut the circle (or arc) and create 4 arcs and stop there (no coloring).

The original object is not deleted.
