Open a Revit Model
When you open a model, you can set options to audit the model for corrupt elements, detach the local model from a central workshared model, or create a new local copy of the central model. Use Revit Home to open a model from BIM 360 Document Management.
Open a Revit Family
Open a family in the Family Editor to modify the family or to use it as the starting point for a new family.
