Im doing well :sweat_smile: sorry Im just a student and dont understand everything fast

This question is so exhausting, this forum really needs some good FAQ page. See here and learn the difference between trimmed and untrimmed surfaces.

I also suggest doing some intro tutorials on Rhino and Grasshopper before diving into plugins.
