Selectively reload Autodesk® Revit® families into Autodesk Revit project.
ReLoad displays a categorized list of all Autodesk® Revit® families in the project and all are checked for reload by default.
Alternatively, you can choose one or more families from the list
+ check a category to reload all families of that category
+ expand the category to select individual families.
ReLoad searches for selected families in the Options/File Locations/Places directory list. If a family is not found, you will be prompted to manually select its location.
