    Precast wall element

    We have a detail for a precast brick element above windows which is an L-shaped piece. What do people think is the best way to models this?

    1. Model it as a simple wall then 2D embellish with a detail item when sectioned.
    2. Create a generic family in the correct profile so it automatically sections crrectly.

    I've discounted using a wall sweep as they always export as IFCobject and we need this to be a wall.

    Ive done those as Families. Generic Models, or Structural Framing (when they were structural lintels).

    Thanks Aaron, do you apply them to any specific family type? It's more to do with what category they export into when i create an IFC. I was thinking specialty equipment (why the hell isnt it speciality equipment it bugs the life out of me!!) so that it isnt just an "object" in IFC

    Rob, read up on IfcExportAs and IfcExportType parameters, then the Category in Revit can be overridden in de Ifc export and the Category in Revit can just be the best solution for the model in the Revit environment.

    The problem is that whatever category we choose in Revit it isnt going to be the only item in that category and so we can't change the ifc export settings as it will apply to all items within that category. that's why the wall sweep problem is so silly. It would be really easy for Autodesk to make it so wall sweeps exported as ifcwall instead of ifcobject.

    That is why I'm pointing you to the existence of parameters with which you can override the IfcClass on Export on an element or element type level instead of on an Category level.

    The first result in Google is a how-to from Autodesk:
