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
Add additional "standard scales"
To create additional "standard scales" in AutoCAD, type SCALELISTEDIT. You will then see the Edit Scale List dialog, shown on the right.
Click on the Add… button. In the Add scale dialog, enter the name of the scale, for example "1:1250", this is the name that will appear in the list. Then enter the Paper units and Drawing units as desired.
Note: "Drawing units" refers to the modelspace units.
