CAD-tip guru Leonid Nemirovsky sends us a small tip that can save you time by reducing keystrokes when editing dimensions in AutoCAD.
"Instead of using the DimEdit or DimTEdit commands, I use DDEdit. For a shorter version, type ED on the Command line (if you haven't changed the two-stroke alias for it). This works exactly the same way as the other two commands, and as an official command on dtext/mtext."
Notes from Cadalyst Tip Patrol: If you want to edit the string of text in your dimension, then yes, absolutely use ED, but that's all it will do for you. For this purpose, there is no quicker method. Type ED on the Command line and pick the dimension text to alter. If you are looking to change other characteristics of your text (rotation, justification, alignment, etc.), then you need to keep using the DimEdit command. With DimEdit you can return your text to its home position, edit the text string, rotate the text object, or oblique the dimension itself. With DimTEdit, you can change the location of the text (left, right, center, or home) or rotate the text. DDEdit lets you edit single-line text, dimension text, attribute definitions, and feature control frames.
