I'm building a Revit 2024 add-in that places a circular void hole where the user clicks in the model.
The hole family has a “Diameter” parameter and cuts only structural framing members around the click point.

Revit shows this error when the add-in tries to load the family:

Cannot load family: Truss_Hole_GenericModel.rfa

I am NOT using embedded resources anymore — I switched to a fixed file path:C:\RevitPlugins\TrussHoleAddin\Resources\Truss_Hole_GenericModel.rfa

  • The .rfa opens manually in Revit

  • The path is correct

  • Permissions are normal

  • The file is not locked

  • The family is a simple Generic Model with a void

  • The same family loads successfully when manually loaded

Is there any special requirement for loading families containing voids?
Or something specific about loading Generic Models in Revit 2024?
