Dear guys:

Some friends sent me some e-mails asking for more info on the piercing (and some other) relationships and their use on lofting, so I prepared this little tutorial for them. I know that this does not cover all the possibilities, but I hope that them get some help from this...

So, let's begin...

This was a very concise and thoroughly illustrated tutorial. There is much insight packed into this one page. Thank you very much for your hard work in making this information available. The only problem that I ran into was the thickening of the surface. I did some research and found out that if there is a singularity, that is, if the UV curves merge into a single point, thickening won't work, unless you use a crazy microscopic thickness value. I haven't figured out how to create the loft w/o the face curves merging into one point though. 

 

Thanks again! Do you have any books available?
