I found an old tutorial video from 2013 on Maestro's "Structure Sculpting" tool for building peptides, which seems really useful to me. However, I currently have the 2020 version of Schrodinger, and I cannot find the the "structure sculpting" tool anywhere; the closest thing I found was the "Sculpt Complex", which is not applicable for my situation. Is the peptide structure sculpting tool no longer available, or is it now under a different name? Thank you!
