    diffuser family issues

    i just started at a new firm and they have alot of families that do not work they want. So i started fixing some them as problems arise. How ever i modified there diffuser. It seems to work right most of the time but sometimes when you align it to a ceiling grid it will grow and not shift. to add to that it is not every diffuser its just some of them.

    I also can not recreate this in another project file

    No revit atm so cant see your family. First thing i would do is review the strong/weak/none settings for the reference planes. Typically, strong will stretch the family, weak will move the family and none won't even be seen in the project.

    Because the parameters in the family are Instances, they are trying to look for the size in the project. I would make the TERMINAL SIZE parameter a Type Parameter instead of an instance since the family itself is using types for the varied sizes. If you just modify that parameter it should be fine. Hopefully that will fix your issue.
