AutoCAD Productivity
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
Lock your viewports!
The zoom factor of your viewports is crucial because it affects the plotted scale of your drawing. So, once you have set your viewport scale, it's a good idea to lock your viewport so that you don't inadvertently change it. To lock a viewport, select it in paper space by picking on its boundary and then right-click anywhere within the viewport. Select "Properties" from the right-click menu and the Properties panel will appear. In the "Misc" section, click on "Display locked" to activate the pull-down and set the value to "Yes".
