Updating Panel Schedule Block Already on the Drawing

Monday, August 23rd, 2010

After you customize a panel schedule block, you need to redefine the block in any drawings where the schedules have already been inserted.

The simplest way to do this is to open the drawing where the panel schedules appear.

  1. Erase all panel schedules from the drawing.
  2. Type PURGE at the command line.
  3. Press the “Purge All” button.
  4. Answer “Yes” or “Yes to All” to any prompts that AutoCAD shows you.

This process will remove the block definition from your drawing. Now you should reinsert the panel schedule on the drawing.

Insert one and confirm that it appears correct. If it does, insert the rest of your schedules. If not, go back to the original drawings, make changes, then repeat this process to update your drawing.

Other Ways to Redefine Panel Schedule Blocks

There are two other ways to redefine blocks in AutoCAD. In addition to being more complicated, the other drawback to these two methods is that attribute definitions will not be updated when this happens. Any changes you made to the attributes will not be reflect on the drawing. Unfortunately, this is a limitation of how block updates work in AutoCAD.

1. You can use the “DM Electrical->Customization->Blocks->Redefine Block on this Drawing” command. You will be prompted to select the block to update. You will have to browse to the location of the block on the system and select it.

2. You can also use the standard AutoCAD INSERT command. Use the “Browse” button on the dialog to select the block you want to redefine. Once you have selected the block, you can ignore the rest of the settings and press OK. You will be prompted if you want to redefine the block in the drawing. Answer “Yes” to this prompt. You can then cancel the INSERT command. It is not necessary to insert the block on the drawing to redefine it.

    OK… I have a LARGE project and I just changed the format of the schedule blocks – moving the attributes. Can’t you incorporate some automation of the redefine, erase, replace so this works better?

  2. I’ve added your suggestion as a request to the wishlist. You can vote for it there if you would like us to spend some time for the next release implementing this feature.
