Revit family creation refers to the process of creating a library of building products or mechanical components, most commonly using Autodesk Revit platform. The main advantage of this part of Revit modelling is that whenever any change is made to a family type, it is instantly updated and reflected throughout the project which uses that family type. For instance, if the dimensions of a window type is changed, all the windows of same family are instantly updated throughout the project. Such Revit families are called Parametric Revit families. By using parametric families in Revit models the project owner is able to maintain a centralized BIM model for the project.
