Update the Source File Block Edits on the Tool Palette
From: AutoCAD Productivity Articles #139
Originally published: April 2015
Throughout the archives of Michael's Corner you will find dozens of references to tool palettes, including the key component of blocks on a tool palette: the Source File. [Coverage of the Block Source file was originally presented in March 2006.]
Scenario: You add this armless chair to the source file and put several chairs in a drawing… then you update the chair in the source file with arms.
Problem: The chair on the palette now displays arms, but the chairs in the drawing have no arms, soooo…
How to Update Drawing Blocks from the Source File
After modifying the block in the Source File, right-click on the related block on the tool palette, then click Update tool image.Now, in the drawing containing the blocks that were in the former armless state, go to the tool palette, right-click on the updated block image, then click Redefine… and all those chairs now have the updated condition with arms!

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.
