| Description |
|---|
| Cut a circle(s) or arc(s) in multiple arcs, the arcs created can be coloured alternately to distinguish. The new circle is created in the real coordinate of object, not in the coordinate of the Body. (Command line, paste this complete macro in the Python console).

Description
This macro cut a circle(s) or arc(s) in multiple arcs, the arcs can be coloured alternately to distinguish.
CutCircle
Use
Copy the macro cutCirle complete in the Python console FreeCAD select the circle(s) and (or) arc(s) type in the console:
to see the circles and arcs cut here in the example 5 contiguous arcs.
The original object is not deleted.
