I have just started using AutoCAD 2007. During the transition I have both 2004 and 2007 on my laptop. In AutoCAD 2004, I switched to model space in a view port, turn on orbit, right-click to sellect more and pick adjust clipping planes to adjust the front and back planes to focus on the views I want to isolate. That feature is no longer there when I right-click in the same enviroment in AutoCAD 2007. How do I adjust clipping planes now in 2007? Where is that feature moved to?
