Update the Source File Block Edits on the Tool Palette

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

2D Drawings from your 3D Models

Flatshot

Over the years, there have been various methods of creating 2D drawings from 3D models in AutoCAD. In the early days, we used export to DXB, a file format that is no longer supported. Then came the FLATTEN command. Now, there's a new command that's better than previous methods.

The FLATSHOT command creates a 2D block object of any view that includes 3D solid objects. There are a number of options including show/hide obscured lines and independent control over the colour and linetype of foreground and obscured lines. Flatshot works by projecting the lines of your current view, not UCS, onto a plane. This is a little more versatile than Flatten and doesn't seem to skew the dimension of the object, which Flatten is notorious for. It also has the advantage of leaving the original object as is. The only downside is that it seems to have problems with perspective views. Parallel projection views work perfectly.
