AutoCAD Productivity
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
Mid Between 2 Points (m2p)
Sometimes you might want to find a point midway between two other points. In the past, you might have drawn a line between these two points and then used "Snap to Midpoint" but this requires the drawing of a construction line and isn't very efficient.
Enter the m2p object snap. This will find the midpoint between any two picked points without the need for a construction line.
How it works: Say you want to draw a circle midway between two squares, start the circle command and then enter "m2p" when prompted to specify the center point. Now just follow the prompts.
Command: circle
Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: m2p
First point of mid: (pick first point)
Second point of mid: (pick second point)
Specify radius of circle or [Diameter] <20.000>: (pick to complete circle)
