IFC parameters that control export mapping of elements are included for elements and types by default. Use the Export Mapping dialog to change IFC entities and predefined types used for export.
The following default IFC parameters have been added to all elements and types. These parameters control how the elements and types are exported to IFC files. See Specify IFC Entities for Families.
Instance parameters
Type parameters
A dialog helps you map IFC entities and predefined types to family instances and types. The dialog allows you to select the IFC schema and then search for specific IFC entities. Select the entities and types in the dialog, and they are applied to the parameters on elements in your model. The same dialog is used to control the entities included in your IFC exports. See Specify IFC Entities for Families.
