the above code led me to revisit my cookie cutter code (trying to use max's editable poly cut routines was a fools errand, quite frankly it's a flakey load of rubbish). Anyway it's always easier creating new mesh from scratch so I delete the underlying in mesh and then fill in the holes.
my head hurtsit's a long way from release but will probably looking for beta testers who don't mind their max being fried
Wow, that's neat. Definitely sell that.
