Original Dimension Value
From: AutoCAD Productivity Articles #143
Originally published: December 2015
Since the dimension text of an associative dimension is Mtext, double-click anywhere on an associative dimension and you can add additional information… or modify the value to what you want.

But what if you want to put the dimension back to the original value?
Insights:
If you reposition an extension line origin grip of a dimension and the value doesn't change, the original value was modified.
If you double-click a dimension and the edit box has a white background — not blue — the original value was modified.

Solution:
Double-click the dimension, then put the less-than and greater-than characters in the dimension box, like this… <>
The original value will be restored.

Tip of the Day
Repeat for Efficiency
Sometimes, you may find yourself having to use the same command repeatedly. This can be a pain, unless you are aware that the previous command can always be repeated by hitting the Enter key on the keyboard or by using the right-click mouse button and selecting the name of the command you just used. Both these methods are more efficient than repeatedly finding a command on a toolbar or from a pull-down menu.
What's more annoying than having to repeat a single command (and more common) is having to repeat a sequence of maybe two or three commands. Obviously, you can't use the "Enter to repeat" trick. However, the right-click menu has another option that can help in these situations. Below the name of the last command used, is a menu option that says . If you select this option, you will see a list of all the commands used in the current drawing session, with the most recently used at the top.
Using this method, you can repeat any sequence of commands without having to return to a toolbar or pull-down menu.
Note: This function is controlled by the inputhistorymode variable.
