Hello Michael:

1.- I think that I had an accidental non-desire situation.
If I draw any closed curve, and a path touching the curve, and after that I apply a 1 rail sweep-->Flat-->Set flat direction and I choose a diagonal direction I get a weird result. How this was the first example I was searching, I was coming back again over the same, and I was forgotten the original sense of "Flat" parameter.
I put a image for explanation. Don´t pay attention to the other lines, I only was testing things.

2.- About ArrayGem: Thanks, I saw your notes after. I always ask the questions and after read about that :-(

3.- About Active Style, very thank you! I´m sure that there are any note from you before, but.....(see 2 paragraph) :-)

4.- About images. I don´t know how and why, but I had blocked the images from this site. I had this problem 2 months ago...anyway..fixed.

Bye!

David
