Lynn McCann shares a simple and easy tip to set the angle of your view in an AutoCAD viewport.
"Apply the DView command, then the Twist function, to rotate a view in a viewport. When you're finished, always lock the viewport to retain the display."
Notes from Cadalyst Tip Reviewer Brian Benton: DView is an older AutoCAD command, but it has many aspects to it. This tip describes its ability to rotate the view of your viewport. It’s nice because it is very straightforward and simple to do. You don’t have to create a named view or alter the UCS.
Activate your viewport, type DView on the Command line, and type TW for the Twist function. Select an object; any object will do. Type in the angle you want your view to be rotated, and close the command. It really is that simple.
