Fabrication References – 2023 Update

Fabrication 2023 is out. I’ve updated all the reference information to include 2023 formats. As has been the trend the last few years, little has changed. Summary below…

COD Script Updates – 2020.07.08

I’ve made a couple updates to the Autodesk Fabrication script libraries. If you use them, you can download updated versions from here.

Scripts have been updated to include the Connector Material property found on CID/Patterns 522, 1522 & 2512 as shown below…

This property is intended to be used by a connector to specify a alternate material the connector can connect to. This allows a coupling to connect to alternate materials such as with transition couplings.

Credit for discovering the COD function to extract this property goes to Liz Fong at MacDonald Miller Facility Solutions in Seattle, WA.

Note: This property has also been added to the list of COD Item Properties located here.

Scripts Updated

    • Debug ITEM Connectors.cod
  • Job Item Scripts
    • WriteAllConnectors (Job).cod
    • WriteAll_Props (Job).cod

I’ve made a couple updates to the Autodesk Fabrication script libraries. If you use them, you can download updated versions from here.

Scripts Updated

  • Job Items
    • All Scripts updated to now include the Item Number which makes it easier to track back report entries to ITM’s in your job.
    • Fix a couple syntax issues in a few scripts which caused errors.
  • Revit Support Report
    • Added Reporting on Revit 2020 status
    • Changed CID/Pattern # 1175 from NO to YES.

Scripts Updated

  • Debug
    • Debug ITEM Library.cod
    • Debug ITEM Sealant.cod
  • Job Items
    • WriteAllLibrary (Job).cod
    • WriteAllSealant (Job).cod
    • WriteAll_Props (Job).cod
  • Library Items
    • WriteAllLibraries (Library).cod
    • WriteAllSealant (Library).cod
    • WriteAll_Props (Library).cod

Issues Corrected

Issue 1: Scripts accessing the “Library” property were failing on CID/Pattern 2199. Scripts have been updated to watch for this and report it as an ‘Unknown‘ Library.

Issue 2: Some CID/Patterns can be configured to be pipework or duct work depending on the “Pipework” option’s “Yes/No” status. Scripts were updated to properly report or ignore this property depending on the Sealant value being present.

If the option is set to “Yes“, the pattern is a pipework item. If set to “No”, the pattern is a sheet metal item. Sheet metal items contain the “Sealant” property where as Pipework items do not.

This condition is present in the following CID/Patterns…

149838 902110112381239
12401241124212471248

Special thanks to Kyle Speropoulos of MMC Contractors in Kansas City for alerting me to this issue.

Buying ITM Content

If you use Revit’s Fabrication Parts, CADmep or any of the other Autodesk Fabrication products like ESTmep or CAMduct, you use ITM content. ITM files can be tricky and time consuming to build. If you don’t want to tackle it yourself or just done have time, I recommend Virtual Building Supply (https://itembuilders.com).

There are other companies that will build ITM content for you but their quality varies. Nibco as an example, is two companies removed from the firm that produces their content. As that firm has had some questionable business practices, I won’t get into detail other than to say I can tell just by looking at an ITM if they created it. If they did, I won’t use it.

There’s a few Autrodesk resellers as well who will build ITM content slightly cheaper but don’t put the quality or extra data associated with it into their work.

Virtual Building Supply on the other hand is run and operated by industry insiders. They’ve installed pipe. They’ve managed Autodesk Fabrication databases. They know their stuff.

If you browse to their downloads page, the have a few things you might be interested in…
