1. Here is my attempt at explaining it further...Let me know if its not clear...
(see image below)

2. That would be great!!!

3. Curves from isoparms would be even better!!! :) sometimes when looking at wireframes, i kind see the value of
attaching things and/or snapping to isoparms, even reconstructing parts of the surface using some of them or creating
new surfaces through re-wiring....no particular example right now though, but i might come back to you later with it. :)

BTW, Thanks for responding so quickly. I really enjoy working with MoI. Kudos to you for putting it all together.

Best,

Luis



I've also attached the file for anyone to see and experiment.
