How to 'crop' a g-code

[magicniner]

If you can code in c++ or c# or Delphi i can recommend Angus Johnsons excellent freeware 'Clipper' http://www.angusj.com/delphi/clipper.php

That looks like a really useful bit of software written by someone with an understanding of the problems involved in truncating lines with a shape, but surely the problem with G Code is "Simple" ? :D
