Update the Source File Block Edits on the Tool Palette

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

Object snap tracking

object snap trackingFinding the centre (centroid) of a square or rectangle used to require the use of at least one construction line but with object snap tracking, the same point can be found without having to draw any other objects.

This technique relies on the fact that "Midpoint" is set as one of your running object snaps and that polar tracking (POLAR) and object snap tracking (OTRACK) are on. Say you have a square and you want to draw an inscribed circle. Start the circle command and then hover the cursor over one of the vertical sides of the square until the midpoint snap icon appears. Move towards the centre and a dotted tracking like will appear. Next, hover the cursor over one of the horizontal sides of the square until the midpoint icon appears, again, move towards the centre of the square. This time, when you get close to the centre, both horizontal and vertical tracking lines appear and you can snap to the intersection simply by left-clicking. Finish the circle by snapping to any midpoint.
