Help - how do I trim or split a curve but leave a copy of the cutline on the trimmed object (Ai minus front)

Hi

Have you tried using the _CurveBoolean command?

http://docs.mcneel.com/rhino/5/help/en-us/commands/curveboolean.htm

The CurveBoolean command trims, splits, and joins curves based on their overlapping regions.
Pay attention to the command-line options:

DeleteInput

  • None

  • Deletes no input curves.

  • All

  • Deletes all input curves.

  • Used

  • Deletes only the parts of the input curves that correspond to the newly-created curves.

CombineRegions
Appends the selected regions to the previously edited regions.

Thankyou for the response I was trying boolean but I didnt see curve boolean thankyou

Wow thankyou first time Ive used this forum and its the first time I got a response so quickly thankyou Answered
