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
Trim Up
Often, you find yourself using the Trim command to tidy up loose ends of lines. If this is the case, don't bother selecting cutting edges, just use the "select all" option.
Start the Trim command, TRIM from the command line. At the prompt, simply hit the Enter key to accept the <select all> option.
from the pull-down menu orNow, just pick the line ends you want to remove.
