Model Listed items for use in Revit 2022 and newer

[Jason_Sherwood_]

It would be nice if Autodesk would make it standard that when converting Pattern 928 to Pattern 1175 all item properties are read from the 928 and applied to the 1175 and then make it add all common and product listed item properties to a model list of 1175's when you create a model list including diameters as well.

As it stands now the process is almost laughable.

1. For each size of Model item you need to use the Convert3dmodel command which will give you a pattern 928 use the connector block to identify the connector shape and size. 
2. Set all the item properties and connectors 
   
   

1. Right Click in the white space of the folder where your 928's are and select the new 3d model item command to turn each of the 928's into 1175's. 
   

 

1.  Once you have all the sizes of the 1175 built make sure all the item properties and connectors are what you want with those by repeating step 2 again, they will default to ductwork and also some bizarre materials etc. I don't know why they don't inherit the properties of the 928..... I think I'll write a ticket on that because this is a tedious process.
2. In the folder where the 1175's are right click and create a new 3d Model list of the 1175's, use Ctrl to select multiples once you have browsed to the folder.
   
3. Once all are selected and you hit open you will once again get to repeat setting all the properties in step 2, have fun with that.
4. After setting the item properties you need to open the product list and add and define the Diameter #1, and Diameter #2 Sizes.
   

You now have a Model listed part, you can add fields to the product List along with any Custom data you may have in your database.

1175 wasn't ever suppose to be supported. In fact, all the patterns are expected in Revit, they just intentionally block many of them. 

1175 just slipped through the cracks and once it was out in the wild, it was impractical to pull it back.

Not sure if they pulled it but at one time there was a debug flag that allowed ITM Assemblies to work in Revit too. I never shared the info as if the flag ever want away so did your content so I didn't want to risk the integrity of people's models.
