Have you ever wondered if there are API commands for addressing or automating Type Catalog information in Revit? A recent post from Jeremy Tammik covered some of this. In it, he discusses the difference between
- the embedded MEP lookup tables (which the API can address using FamilySizeTable and FamilySizeTableManager), and
- the legacy text file lookup tables, which are basically a specially formatted TXT file with the same name as the RFA.
The post is well worth a read, as he also references some useful resources in the Revit help and an AU class…
What about units in Type Catalogues? Quoting directly from The Building Coder:
Question: we’re trying to create type catalogue in txt file for Radiator family. We were trying to define a parameter in watt units, with no success. How to define header for this parameter?
Answer: Look at page 15 of Martin Schmid’s Autodesk University class handout on Creating Revit MEP Content for Engineering Coordination.
Here is a sample Exhaust Fan RFA and TXT file for you to play with.
They don’t use Watts, but should give the idea if you are not already familiar with type catalogues.
Also, the families guide provides a list of the parameter types, namely, for electrical_power: watts, kilowatts, british_thermal_units_per_second, british_thermal_units_per_hour, calories_per_second, kilocalories_per_second, volt_amperes, kilovolt_amperes, horsepower.

I'm thinking it won't be long before we have some useful custom nodes for addressing Lookup Tables in Revit using Dynamo 🙂
