Syntax
The IFCFamilyInstanceExtrusionExportResults type exposes the following members.

Name | Description | |
---|---|---|
![]() | ExtraOffset | The extra offset determined from the geometry of the family instance. |
![]() | IsValidObject | Specifies whether the .NET object represents a valid Revit entity. |
![]() | MaterialId | The best material id determined for the family instance. |

Name | Description | |
---|---|---|
![]() | Dispose | Releases all resources used by the IFCFamilyInstanceExtrusionExportResults |
![]() | Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
![]() | GetCutPairOpenings | Gets the set of "openings" determined from the analysis of the instance geometry. |
![]() | GetExtrusionHandle | Gets the extruded solid handle generated for the family instance. |
![]() | GetHashCode | Serves as the default hash function. (Inherited from Object) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object) |

The analysis attempts to convert the geometry of the instance into a single extrusion with
additional extruded openings cutting the main solid.
