    Painted Children

    One of the many benefits to our Revit work that Enscape has opened up is a collective desire to make things look nicer - finally - and whilst I'm not one to be drawn into conversations regarding linework, I am willing to entertain chats on materiality.

    And so, to a new (?) discovery... parameter-painted faces on children families don't appear to come through an adult.

    Example, showing our (shared) "shelves" in the foreground, with their (type-based) painted-parameter materials (blue/green) - but the same shelf, arrayed in the shelves-family (of the background) only "pass through" the one material.

    I've not up-ended the family to really find out why - though I have a sneaky suspicion it's related more to the "true" faces of the solid form (i.e. the sketched face plane is proper, the "pulled" side-faces are not) - but thought I'd throw this up here in case there is a "Aha!" one of you knows about.

    You can pass through painted faces, with instance parameters tied to the paint, connected to parent family. Been doing it for years.

    I haven't tried without the instance parameters, though.

    See I was wanting type-based materials as the shelves are swappable - but testing tied-instances, the plot thickens.... some faces come through, others do not.

    ...and changing the plane the shelf's extrusion was drawn in doesn't make any difference either.

    Strange.

    If I'm understanding things, I've run across something similar to this before..... Using <Family Type> parameters and Arrays seems to be tricky. Arrays work best when the members parameters are instance-based. But that removes some of the advantages of type-switching with a parameter (which works best with Type parameters). I've applied at least 2 different solutions to it depending on the complexity - drive your instance parameters with a Type parameter, or change your swappable family to the (nested) array rig instead of the shelf. If your <Family Type> parameter is a Type parameter, you can change the <Family Type> and the Material at the same time (that's the first option). The second option requires all the array & sizing logic to be moved to the array rig family, but you have an option to make <Family Type> an instance (the type parameter that drives the material instance parameters also moves to the array rig).
