Toggle Yes/No Parameters with Formulas
Often times, you’ll want formulas to drive Yes/No parameters in parameter Revit families. There are a few methods for accomplishing this, but I recently stumbled on one that I haven’t seen in my 15+ years of Revit experience. Typically, you will see formulas defined as a toggle and can negate a condition using the NOT…

Programmatically Retrieve all Shared Parameters in a Project Model using The Revit API
A few months ago, I shared a post on OpenDefinery about a simple solution to fully purge Shared Parameters from a Revit project model. In that post, I shared my discovery that Shared Parameters have an Element ID just like any other model element, which means you can select the parameter through the Revit UI using…
