Thanks! That's helpful b/c I've been trying to figure it out for an hour now. However, how should I set up my drawings? I really prefer to have individual sheet files for each sheet that prints (ie, A01, A02, etc). These sheet files reference my plans, elevations, etc. But if I can't change the layers within the viewports, I can't control which floor plan I'm looking at. Any advice on how to set up the sheet files versus the drawing files? I'm floundering...
