    Help - Family Creation

    Hello everyone. This is my first post on here. With all the knowledge, I am hoping someone can help.

    I have created some revit families but I am now wanting o do something beyond my knowledge level.

    Specifically, I have supply air diffusers which allow you to input the airflow to them.

    Is there any way to make it so that if you enter an air value which exceeds the minimum or maximum CFM listed in the family that I can get the color to change? Typically, my diffusers and grilles are grey. So I would like them to turn bright red or orange if the minimum or maximum CFM is outside the allowable numbers set in the family.

    Thanks very much.
    Nico

    Create an extra solid form that only turns on when your criteria is met. Use a separate material to define a warning appearance.

    Can I have it only turn on when it is not met? For example one diffuser type is set to 648 cfm max. If you input 700 cfm - which is above, the extra solid would turn on?

    This is working well. Thank you Steve. I am having an issue with the color though. The never solid(s) are bright red, but they do not show up like that in my model when I insert the diffuser and test it out. Any idea what I am missing here?

    You probably need to update the object styles in the project. Whatever existing standard you set/change in a family will be overwritten when you load into a project.
