Description

This macro cuts circles or arcs into multiple arcs. The created arcs can be colored alternately to distinguish them.

CutCircle

Usage

  1. Paste the macro cutCirle in the Python console.
  2. Press Enter (the code is now in memory).
  3. Select one or more circles or arcs.
  4. Invoke the cutCircle() function with 1 or 2 arguments from the Python console:
    • Example with 1 argument: cutCircle(4). This will create 4 new arcs for each selected circle or arc and stop there (no coloring).
    • Example with 2 arguments: cutCircle(6, 1). This will create 6 new arcs for each selected circle or arc, colored alternately in red and white as shown in the image.
  5. The original object is not deleted.
