Hi all. Was wondering if anyone had tips for drawing machinery, engines, spachips, industrial equipment and the like. Specifically conceptualizing them. I'm a big fan of MC Barret's work and I understand the basic idea of conceptualizing these machines. My difficulty is in rendering machinery like engines and such. Like I've tried drawing some engines and I just get really confused with all the tubing and literal nuts and bolts of the thing, and the stuff I draw just looks like a mess.
I understand perfectly that I may just not have put enough time into drawing machinery, and of course I'm going to keep drawing and sketching regardless. I just wanted to know if anyone had tips on visualizing and sketching engine parts so as to make them less confusing I guess. Links to tutorials or explanations would be much appreciated.
