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
Selection Preview Cycling
Making positive selections is much easier now that AutoCAD highlights (previews) objects as you mouse over them. However, it can still be difficult to select the right object when drawings become complicated with lots of overlapping objects. Fortunately, AutoCAD allows you to cycle through all the overlapping objects under the cursor.
All you need to do is hold down the Shift key and then repeatedly hit the Spacebar (Shift + Space). Each object under the cursor will be highlighted in turn and you can easily pick the one you want.
You can use a similar technique to cycle through sub-objects such as faces and edges on 3D Solids. To cycle through sub-objects, hold down the Control key and hit the Spacebar repeatedly (Ctrl + Space).
