Hmmm ... Not sure how to explain the situation any better. Okay, say I create a viewport (to model space) in layout view (Click on a layout tab, then click on menu bar, View, Viewport, 1Viewport and make a rectangle in layout view). Now, when I high light that rectangle, right click, and pick properties, I get a window that allows me to change Misc properties such as Standard Scale, Custom Scale, etc.
In AutoCAD 2000 layout view, I can also draw a closed polyline, or other object like a circle and turn it into a view port to model space (click on menu bar, View, Viewport, Polygonal Viewport or Object, and then pick the object in Layout view). Now when you highlight one of these objects and open up it's properties, the properties window does not have the Misc. options to change Standard Scale, Custom Scale, etc.
My question is How do I or is it possible to change the Standard scale/Custom Scale of these Viewports? is there another way to do this?
