Hi Burr,

Wow, that looks great. Thanks so much for following this through. I wonder if that is the technique that Jean-Paul uses?

I need to have a go at this today. I think I understand the technique and will get back to you with results. I really hope I can duplicate what you have done there as this is looking like the method for hull generation.

What a great forum this is. Thanks again Burr :)

Mark
