Most MEP contractors moving to Revit with Fabrication Parts at some point wrestle with renumbering parts. You can purchase tools or add-ins to make this easier or even write your own with Dynamo or C#.
But most contractors aren’t coders. And buying more software can also be a challenge. The good news is that those are not your only options, There’s some well written FREE Revit Add-Ins that make this a breeze.
Head over to DiRoot’s web site (https://diroots.com/) and download the OneFilter Add-In found here and the ReOrdering Add-In found here.
Once installed, you’ll find the tools in the DiRoots Ribbon in Revit along with any of their other tools you may have installed.
The following image shows 2 runs of Rectangular and 2 runs of Round duct work drawn in Revit using Fabrication Parts. One is drawn in a +2in WG service and the other -2in WG service. All duct has a tag configured to display the Fabrication Part’s Item Number property.
First Up – DiRoots OneFilter
Using the DiRoot’s OneFilter Add-In, you can easily select not just Fabrication Parts, but also select them based on their properties.
Once selected, you can see Revit selects the specified items in your model.
Next – DiRoots ReOrdering
Now that your desired parts are selected, you can use the DiRoots ReOrdering Add-In to renumber those parts.
After applying your renumbering parameters, you can see how Revit then displayed the updated Item Numbers for the Fabrication Parts.
As you can see, with a couple free (well written) utilities you can quickly and easily select and renumber your fabrication parts in Revit.
There’s a lot of other reasons beyond renumbering to use some of these Add-Ins. They’re very functional for a lot of workflows. Those uses are beyond the scope of this post but feel free to explore these Add-Ins or some of the other DiRoots tools when you get a chance. They’re some of the highest quality free Add-Ins for Revit than you’ll find anywhere.
