AutoCAD Productivity

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!

Between 2003 and 2016, Michael Beall (and one or two guests) wrote almost 600 articles for CADTutor. The focus of these articles is AutoCAD productivity, and although some of them are now more than a few years old, most remain relevant to current versions of AutoCAD. The article above is just one example. Check out Michael's Corner for a full listing.

Tip of the Day

Using Imprint to sub-divide faces

Imprint in actionThe Imprint command (Modify ❯ Solid Editing ❯ Imprint Edges) gives the first impression of nothing more than adding graffiti to solids. Upon closer investigation, however, we find that it actually modifies the face on which it is placed, effectively sub-dividing it. Sub-divided faces can then be extruded using the Extrude faces command (Modify ❯ Solid Editing ❯ Extrude faces).

Procedure

  1. Create a box.
  2. Draw a line on one of the faces.
  3. Imprint that line on the solid.
  4. Use Extrude faces to extrude the sub-divided face.

To generate this modified part with Boolean operations would not be difficult but, as we all know, speed and accuracy are the name of the game. The procedure describe above can be auto-executed with the command macro:

^C^C_line;\\;_solidedit;b;i;\last;y;;;f;E;\;\\;;

The UI could benefit from some advanced programming, but if one pays attention to the Command Prompts, it's not so bad.

Note: This tip relates to versions of AutoCAD before 2007. Although the technique works with 2007 and above, the same operation can be achieved more easily using the Presspull tool.
