Model Checker includes Family Types without instances

[nino.halilhodzic]

Hi everyone,

I'm using Autodesk Model Checker for Revit (with the Model Checker Configurator) to create a rule that checks whether all Air Terminals are placed on the correct Workset (A_Air Terminals).

My rule is currently defined as:

• Category: OST_DuctTerminal
• Filter: Workset Name ≠ A_Air Terminals
• Check Result: Fail when Matching Elements are Found

In my Revit model, I have only 52 actual instances of Air Terminals (confirmed via a Schedule).
However, when I run the check, the Model Checker reports 131 elements, and for many of them I get the message:

“There is no instance of this type placed in the current model”

This means the checker is also including Family Types without any placed instances, which is not useful in this context.

My question is:
Is there a way to make Model Checker filter only placed instances, excluding unused Family Types from the results?

Or is there a known workaround/filter logic that can be used to achieve this?

Thanks in advance for your help!

You definitely can! You need to add another filter with the criteria of “Type or Instance” and then “Is Element Type” set to does not equal true. 

I’m writing from my phone or I would stick in a screenshot.

This works, thank you Jason!
