I've been doing a lot of woodworking of late, and using sketchup to do a lot of the plans. It hurts my head to see all these non manifold drawings they use. I'm slowly shifting my thought process over to these types of drawings, but still having two faces share the same space is giving me migraines. Like a T Joint where two boards meet. A 3d printable model, that junction is hollow, but in a woodworking design drawing, that face (end of the board) exists.
