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
Cycling through grip modes
When you have a grip selected, the normal mode is to stretch the selected object and AutoCAD displays ** STRETCH ** on the command line to let you know. But did you know that by hitting Enter you can cycle through the other grip modes - move, rotate, scale and mirror?
This is a really efficient way of working and means you can spend less time clicking the buttons on the Modify toolbar and more time editing.
