Type Catalog References
Type catalogs can be referenced by using system parameters and shared
parameters. The format for the type parameter must be
##parameter
name##parameter type##units
; these parameter types and units must
exactly match the format required by Revit.
Here are a few examples of proper formatting:
Duct Width##HVAC_DUCT_SIZE##INCHES
Power##ELECTRICAL_POWER##WATTS
Air Flow##HVAC_AIR_FLOW##CUBIC_FEET_PER_MINUTE
Width##LENGTH##FEET
The following list contains some of the parameter types and their units
that can be used in creating a type catalog TXT file:
