I got a comment from Murray Clack on the last post about saving changes to layout, and wanted to make sure it didn't get lost by just sitting in a comment thread. (And now that's one more post I don't have to write on Plot Previous.)
Let's say you just plotted the drawing but you forgot to check the "Save changes to Layout" check box. Simply start the plot again, and from the "Page Setup" pull-down menu, select "Previous Plot". This will reassign the previous plotting parameters Check the "Save changes to Layout" check box, and then click the "Apply to Layout" button (next to the OK button). Now you can simply click the Cancel button (so you don't re-plot the drawing) and the plot setup has been applied to the Layout.
It's nice to be able to reset the Save Changes option without plotting the drawing twice -- a good use of Plot Previous.
