Are you tired of seeing multiple scale representations of annotative objects? You can turn them off using the SELECTIONANNODISPLAY system variable. 0 = off, 1 = on. I really appreciated this when I found it.
Notes from Cadalyst tip reviewer R.K. McSwain: Here is one of those things you might not even realize is an option until it is pointed out. When you select an annotative object, AutoCAD will show a ghosted image of all of the hidden scale representations. If an object has several scales assigned, this feature can be a bit annoying. Michael shows us how to turn if off with this tip. Thanks.
