I have been working my way through Rhino tutorials, and am doing the one where you loft two surfaces, then trim them. I have attached the part of the instructions that I find incomprehensible.
I cant understand
1. Why you have to draw a line 1/2" "towards the hull surface"
2. What "towards the hull surfaces" means
3. Why trimming the two surfaces results in warped panels.
If anyone can shed some light on the process, it would be really appreciated
