Use the Family Editor to modify existing elements or create new ones to meet the specific needs of a project.
All of the elements that you add to your Revit LT projects are created with families.
By using predefined families and creating new ones in Revit LT, you can add both standard and custom elements to your building models. Families also provide a level of control over elements that are similar in use and behavior, allowing you to easily make design changes and manage your projects more efficiently.
