Adding Wire Numbers to Symbols

You may have symbols that require showing the wire number at each wire connection. This would be a manual process for each symbol. However adding an additional _X#TERM## attribute eliminates that need.

Note the underscore in front of the tag.

Here I simply copy and pasted the original wire connection attributes. I then added the underscore and then made them visible.
    
In this example I made my extra wire numbers font size 0.100 where everything else is 0.125.

And after an 'Swap/Update Block' and a new 'Wire Numbers' through the project, here it is!

Understanding and Customizing Electrical's Ladder Reference Numbers (MLR)

The ladder is unique in that each number running down the side is simple text. Delete these and the ladder continues to function just fine. However the first number is a block with several hidden attributes. Delete it and the ladder is nothing more than dumb AutoCAD lines and text. So in all reality the first number on the ladder IS the ladder. Components and wires will auto-number as if the rest of the ladder is not present. Nothing else is needed! So this post is really about the Master Ladder Reference or MLR block.

The first thing I always do when tackling a subject in Electrical, is figure out what blocks are in play. I open each and take a look at what attributes are in each. This helps me understand why each block acts the way it does. Then I start tweaking and observe the results. So what blocks are at play here?

The MLR Blocks

The horizontal ladder MLR blocks all start with WD_MLRH and the vertical MLR's start with WD_MLRV. In the images below the blocks are in order and shown in both exploded and in use.

Company Wire Numbering - Advancing Wire Numbers By One

This was posted on the Autodesk's Electrical Discussion Group. <<AutoCAD Electrical's Discussion Group>>

Someone needed to customize the numbering to match their company's standard. I decided to tackle this to show how flexible Electrical can be with a little customizing. Well... that and I love a good challenge.

• We make our line reference numbers the sheet number with 000 and increment by 10 for each rung ( The first three rungs on sheet two would be 2000, 2010,2020…).
• Our components are set up like %F%S%N and always end with a zero (i.e FU2010, PB2010, CB2010...) unless there are two components with the same Family prefix on the same line, then the they increment by one (i.e. PB2010, PB2011, PB2012...).
• The wire numbers never end with a zero and the wire number increment with respect to the Line Reference number. -Ex.So on first rung of sheet two the wire numbers would be 2001,2002, 2003 and rung 3 would be 2031,2032, 2033. (It needs to be something like %S%N but the %N needs to increment.)

ACADE seems to only add prefixes to the the end of Line reference numbers. Is there anyway to increment the wire number?

  

The real problem is advancing the wire numbers and components. Electrical will only ADD to the end wires numbers and tag names. I started doing some testing and one thing let to another. Here is my work around to this limitation. As always I welcome comments and suggestions if you see better ways to do anything.
