mjm, Mark Doubleday had a great post/video on creating Plot and Model views, check it out here. Basically what I have started doing is using the Plot and Model view in conjunction with the class and view ports. So for 2D i have the definition layer turned on while the model layer is off and then when I need to make renders, turn the modeling layer back on to do the renders. Then for the final plot, I use view ports to put "2D" definition layer where I need it to be in the drawing. Hope that helps some ... check out the video, it's really helpful and useful.
