VAULTS: how they work, how to draw them and how they are called History of Architecture in Sketches

Hello! In this video I'm trying to explain how different types of vaults were evolving with time, how they work and also I'm showing (really quickly) how to draw them. So, again, it's a mix of history of architecture, construction and drawing. Vaults presented here: a barrel vault, a groin or cross vault, a pavilion or cloister vault, a sail vault, a dome on pendentives, a rib vault, a stellar vault, a net vault. Hopefully it will be useful :) Watching and subscribing is highly appreciated! -ONLINE STORE FEATURING MY DRAWINGS: -ONLINE CLASSES in drawing: -FACEBOOK: -INSTAGRAM:
