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
Easily set properties for multiple blocks in Tool Palettes
Lots of people think that when you have blocks saved in a Tool Palette, you have to each individual block to apply custom settings. What if you have 20 blocks and you want them all to have the same setting? Well, just hold the Ctrl key and highlight the blocks you want within the Tool Palette, then right click on any of the selected blocks to apply global settings.
Also, you can hold the Ctrl key to select your first block, then hold the Shift key to select the last block, then right click on any of the selected blocks to apply a global settings. Makes things much easier than one at a time.
