Family

Family

The Family class represents an entire Revit family. It contains the FamilySymbols used by FamilyInstances.

Loading Families

The Document class contains the LoadFamily() and LoadFamilySymbol() methods.

• LoadFamily() loads an entire family and all of its types or symbols into the project.
• LoadFamilySymbol() loads only the specified family symbol from a family file into the project.

Note: To improve the performance of your application and reduce memory usage, if possible load specific FamilySymbols instead of entire Family objects.

• The family file path is retrieved using the Options.Application object GetLibraryPaths() method.
• The Options.Application object is retrieved using the Application object Options property.
• In LoadFamilySymbol(), the input argument Name is the same string value returned by the FamilySymbol object Name property.

For more information, refer to Code Samples.

Categories

The FamilyBase.FamilyCategory property indicates the category of the Family such as Columns, Furniture, Structural Framing, or Windows.
