This is an Autodesk® Revit® add-in that automates the creation of quantity parameters and populates their values as well.

The ‘Generate Parameters’ tool creates shared parameters for Length, Width, Height, Area, and Volume for any given loadable family in Revit.

Not only it create the parameters, but it also populates their values as well.

It’s a one click process once you are in the family editor environment.

As a prerequisite for this plugin to work, you need to setup the shared parameter file that has the definitions for shared parameters.

This tool could prove extremely useful, particularly in modular or prefab projects that have hundreds of components as loadable families.

It's a conscious choice to create shared parameters instead of family parameters because we want the parameters to be schedulable and taggable.
