AutoCAD Productivity

Update the Source File Block Edits on the Tool Palette

by Michael Beall

From: AutoCAD Productivity Articles #139
Originally published: April 2015

Tool PropertiesThroughout 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

  1. Update tool imageAfter modifying the block in the Source File, right-click on the related block on the tool palette, then click Update tool image.

  2. 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

Add additional "standard scales"

Edit Scale List

To create additional "standard scales" in AutoCAD, type SCALELISTEDIT. You will then see the Edit Scale List dialog, shown on the right.

Click on the Add… button. In the Add scale dialog, enter the name of the scale, for example "1:1250", this is the name that will appear in the list. Then enter the Paper units and Drawing units as desired.

Note: "Drawing units" refers to the modelspace units.
