Stevie: Yeah, I need to mirror on an arbitary axis so Ross' code doesn't help, I'm afraid.
David: Gulp! Thanks for the code. I'll see if I can make use of it but judging by the heavy maths involved, I can't see it being any faster than simply calculating each normal from scratch. I didn't think to look at Mark's geometry code.
Cheers
