given for the Nominal Diameter parameter, and that value is applied to the
FOD parameter. If the Nominal Diameter value given in the family does not
match one in the table, then Nominal Diameter + 1/8″ is used for the FOD.

For additional information on working with parameters in family files,
another good reference point is the Autodesk Families Guide, which can be
accessed from the Autodesk Help site:
Help Revit Users Build the Model Revit Families.
Using Shared Parameters
Shared parameters are the most versatile parameters you can use, but they
also require the most management. Used properly, shared parameters can
help ensure that your schedules are coordinated and that your construction
documents are reporting the correct information. Shared parameters can
be type or instance parameters that are used in families or as project
parameters. The main advantage tousing shared parameters is that thedata
they hold can be exported or reported in tags and schedules.

similar to a library of model components.
