Defining a Type Catalog File

When defining a Type Catalog File (.txt) the first row is formatted to tell Revit the parameter name, the parameter type, and the units... such as:

<paramname>##<paramtype>##<paramunits>

However, it is not always obvious what to use for the type and the units.

Instead of trying to remember where this is documented, you can export the family types, and the file will be created for you:

From within Family Editor, click:  Application Menu > Export > Family Types

The following definition will generate output similar to the following:

,SomeText##OTHER##,SomeTemp##HVAC_TEMPERATURE##FAHRENHEIT,
SomeNum##OTHER##,SomeDensity##HVAC_DENSITY##POUNDS_MASS_PER_CUBIC_FOOT
