AutoCAD Bugs

Block thumbnail icons do not display in AutoCAD Design Center

Written by Allan, 18 May 2002

At least applies to:

AutoCAD 2002

Problem:

A drawing holds a number of blocks internally. I am using the ADC (AutoCAD Design Center) to drag and drop them into a new drawing. However, the thumbnails previews of the blocks are not showing up - why?

Reason:

In the AutoCAD Design Center, blocks created in older versions of AutoCAD will not display icons or thumbnails. These blocks receive a typical thumbnail instead of an actual picture of the block.

Solution:

The BLOCKICON command will create the thumbnails for the blocks that has the typical thumbnail.

To restore block thumbnails:
1. Open the drawing that contains blocks that displays the typical thumbnails in the DesignCenter.
2. Type BLOCKICON at the command line and press, ENTER.
3. At the "Enter block name (*)" prompt, enter an asterisk (*) or press ENTER to update all blocks, or enter the name of the block you want to update. These blocks now have a pictured thumbnail.
