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.
