does /sci/ have some memory mnemonics way to memorize complex shapes like anatomy, machines? maybe from geometry?
pictured left here is my attempt to draw the right one from memory, and despite having high interest in memorizing them so i can draw without referencing, i quickly forget the subject and was pushed to fill in the blanks with things i know. the result is similar only in silhouettes but not details...

so i ask science for having so much matterial to remember,
would geometry know a way to memorize all these nooks and cranies of the form on the right, indentations, bevel and their positions, so that one can reproduce the subject into different angles casually and maintaining correct details?
