I can’t recommend Diego’s courses enough! When he first started developing the plugins for Rhino and GH, I was lucky enough to manage this project from OCL’s side.
I’m saying lucky because my experience with parametric design was minimal (if at all) back then, and through Diego’s guidance, I understood all the basic principles to conduct full studies on my own!
For anyone interested in doing LCAs within Rhino & GH, I recommend watching Diego’s videos. He covers pretty much every aspect in great detail and he even looks into optimization techniques (Which I’m pretty certain lots of designed would be interested in)!
