SpatialElementBoundarySubface.GetSubface

Method
Description:
Returns a face that represents the portion of the room face bounded by the boundary element.
Remarks:
If the spatial element's face is adjacent to multiple bounding elements (such as two different walls), there will be one sub-face for each portion of the spatial element's face where it is adjacent to one of those room-bounding elements. This is equivalent to the return of GetRoomFace() if the entire room face is created by the boundary element.
Syntax
