I don't use presently the elevations with the Auto Paint for a couple of reasons;
1- We don't print drawings in color because we often have to print 20 to 30 sets of plans for a new model and 15 to 20 per house built which makes it to expensive for plans that are going to be steeped on and ripped.
2- When the drawing is saved, the paints are not crisp enough (Front with textures) as when you're generating them (Auto paint). Since they're not clear enough, it doesn't provide good black and white printing. Aldo, don't know why there's also missing paints (ex. columns).
3- Playing around with it, I forgot that a huge problem is that sometime, when I edit the 3D Options, when I exit sometime the paints are offset from their original position (Offset textures).
