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
Repeat for Efficiency
Sometimes, you may find yourself having to use the same command repeatedly. This can be a pain, unless you are aware that the previous command can always be repeated by hitting the Enter key on the keyboard or by using the right-click mouse button and selecting the name of the command you just used. Both these methods are more efficient than repeatedly finding a command on a toolbar or from a pull-down menu.
What's more annoying than having to repeat a single command (and more common) is having to repeat a sequence of maybe two or three commands. Obviously, you can't use the "Enter to repeat" trick. However, the right-click menu has another option that can help in these situations. Below the name of the last command used, is a menu option that says . If you select this option, you will see a list of all the commands used in the current drawing session, with the most recently used at the top.
Using this method, you can repeat any sequence of commands without having to return to a toolbar or pull-down menu.
Note: This function is controlled by the inputhistorymode variable.
