    <Family Types...> How does this work?

    How do we control other parameters with this, "Type of parameter?"

    #2
    The only parameter that accepts a Family Type parameter as part of a formula is another Family Type parameter.
    There must be a better way...

        That’s not exactly correct.

        For example; if I have two FT parameters, one that I expect users to change, and one I don’t expect them to change (and they better not or things start breaking), I can use them in conditionals for other formula.

        if(FT1=FT2,true,false)

          This is going to be hard to see (not to mention describe)
          I use one set of Boolean parameters that determine what kind of soffit my Wall Cabinets have.
          Each nested Soffit family has a dedicated Family parameter
          Then there's a Family parameter that actually controls which nested family is active.
          Finally, there's a formula that sets the actual parameter to one of the nested ones based on the Booleans

          Works with only three or four nested families, but it gets real complicated real quick.

            Crazy idea perhaps, and OT, but consider making your soffits shared/nested Generic Models and you'll be able to join them in the project to remove the lines between adjacent units.

              What I am wanting to do select a family type in the drop down list and that item become visible and the others shut off.

                You need a yes/no type parameter that can be applied to the visibility parameter of those items.

                  Well, that is the purpose of the family type parameter. You select one option from the drop-down menu, and that option replaces the others. No need for visibility parameters or formulas. Is there anything else that we are not understanding?

                    I have about 20 generic annotation families that I am wanting to choose from. I want to make a selection and it becomes visibile. I tried creating a generic annotation then created a Family Types parameter, set it to instance parameter, loaded all the generic annotations per the dialog box that loaded. Then loaded it into the project. When placing the family in the project nothing appears.
