    Parameter mirror define

    Hi all,
    I have question about Revit Family Type parameter.
    I have one geometric, for example type right, can I add Family Type parameter who define me a mirror changes for type left?
    One geometry, two versions of left/right positioning in family/project.

    Thank you for all answers !!!!

    The best way to do this is to model both sets of geometries, then assign visibility parameters to each one. That way you can check or uncheck the visibility according to what you want to see. (You can do this as a type or instance)

    Thank you for fast response AFatRat !!!
    I know that method, but I have imported high resolution geometry, and i try to optimize file weight.

    What is "imported high resolution geometry"? Does that mean that you are making families by importing .dwg content?

    That is a "shortcut" to making families that is not recommended. Why? For the following reasons:


    • Imported .dwg geometry is usually modeled with the higher modeling capabilities of AutoCAD, which brings too many surfaces and filleted edges into the family, creating more lines than is necessary and usual in Revit.
    • Imported .dwg geometry usually will not respond to length parameters. It's not parametric.
    • Imported .dwg geometry usually brings undesired colors to the Revit projects.
    • Imported .dwg geometry usually brings undesired linetypes to Revit projects.
    • Imported .dwg geometry is an usual suspect for corrupting Revit projects, including central files!


    Solution: avoid the shortcut, learn how to model in Revit, with simplified geometry.
    Alex Cunningham and jmk like this.

    Thank you for response.
    My problem is: I need good quality of mesh ini Revit. Smooth surfaces, filleted edges. All products will be elements for bathroom: Wc's, basins ect.
    Thats why I use imported SAT format for Revit.
    I have problem only with your last piont:"
    • Imported .dwg geometry is an usual suspect for corrupting Revit projects, including central FILES"

    I'm worry about it. Anyone had already problems with imported geometry- in SAT format?

    Imported sat files cause all of the problems that Alfredo mentioned above, including file corruption. The performance degradation is serious enough that as an architectural user I would never use any of your content simply because that's how you built it.

    Having said that, addressing the original question: making a left and right type inside the family is pointless, because someone can still mirror the left one in to the position of a right one.

    The API is aware of which families have been mirrored, which ones have been flipped, which ones have been mirrored and flipped. The only way to do it correctly is to use an API plugin to monitor the ismirrored and isflipped parameters, and an instance perimeter that defines it as left or right based on those 4 options of the 2 hardcoded parameters.

    It is possible build sculptured forms like toilets and basins natively in Revit, and it makes for a much better family. It just takes some pr

    Shouldn't this thread be moved to the Architeture: Family creation forum? It isn't about structural families.
