    Problems with Bim object

    Hello I am having a bit of a problem.
    I am trying to create some Polycarbonate cladding on a small building I am working on.
    So I go to the Bim store and download an Assan Panel G1000 Greca Polycarbonate Panel.
    Luckily this an *.rfa file. (Some bim objects are actually *.rvt file. How are you supposed to use them?)

    I load my *.rfa file into the building *.rvt file.
    But where is it?
    In the original rfa file, under family categories and parameters, it says Curtain Panels doors and windows.
    But when I look under all three categories to insert family object I cannot find it anywhere.
    Any idea what I am doing wrong?

    Alternatively I could try making my own profiled cladding. I suppose I just sweep a profile along a sinuisoidal curve. Does anyone have experience of this?

    Thank you.

    You would need to draw a curtain wall, and then switch the panels to the type you loaded in.

    Rvt. files are used to share system families (walls, floors, ceilings, etc.) that can't be saved to an rfa file. Once downloaded the types can be be transferred or copied into a project.

    I am trying to create a wooden door frame with polycarbonate cladding.
    I try inserting the cladding into the door rfa file. I thought this would be a simple exercise in creating a nested family but Revit won’t let me do that. Why is that?

    You said the family is a curtain wall door. Curtain wall doors must be used in a curtain wall, and can not be used in a regular door family.

    Ok if I hover over a storefront curtain wall I can tab to a system panel glazed and replace it with the new polycarbonate panel. If I want that mounted on a new timber frame door how would that be possible?
    Thanks

    You aren't going to be able to put a curtain wall door into a regular door family, if that is what you are trying to do. Is your existing door set up to use a nested door leaf?

    Thank you for your reply.
    To create a nested family you simply insert a previously created family into another family?
    I realise there are other issues such as the shared parameter etc so what is the correct approach?
    Must this be a component?

    Another approach might be to use the glazing tool and insert some sort of profile. That seems to be the preferred approach of some people. What are your thoughts on this?

    You can create a sinuisoidal curve profile; but can you use it in the family editor?? That is the question.

    Using profile of sheeting we can avoid increased amount of faces and family instances in the model. What are your thoughts?

    Some family types can't be nested into (or at least won't work) other families. I suspect curtain wall families are one of the exception, but have never tried. I'm not sure what you are referring to by "glazing tool".

    It might help to explain (with pictures) what you are trying to get and why.

    What I am trying to do is create a timber framed door withpolycarbonate cladding on its face.
    If you look at attached photo you will see a building by FTarchitects in Japan.
    Something similar to this is what I am after, obviously withhinges, probably created with references lines, rotational parameters etc.

    Looks to me like wooden framing with the polycarbonate shell. So model it that way I'd say. So structural framing and a wall for the polycarbonate. Then you can build a door to match the wall and insert that into the wall.
