Provides a container of all Revit built-in FailureDefinitionId instances. 
 
The BuiltInFailures OverlapFailures type exposes the following members.
Properties
| Name | Description | |
|---|---|---|
|     | AreaBoundaryLinesOverlap |  Highlighted area boundary lines overlap. Color fills, area tags, and areas may not behave correctly.  | 
|     | CurvesOverlap |  Highlighted lines overlap. Lines may not form closed loops.  | 
|     | DivisionSketchOverlap |  Curves in the sketch of the Division overlap.  | 
|     | DuplicateFabricSheet |  There are identical Fabric sheets in the same place. This will result in double counting in schedules.  | 
|     | DuplicateInstances |  There are identical instances in the same place. This will result in double counting in schedules.  | 
|     | DuplicatePoints |  There are identical points in the same place. Lines created from points may not work as expected.  | 
|     | DuplicateRebar |  There are identical rebar in the same place. This will result in double counting in schedules.  | 
|     | FloorsOverlap |  Highlighted floors overlap.  | 
|     | LevelsOverlap |  Highlighted levels overlap.  | 
|     | OverlappingElementsTest |  There are overlapping structural framing elements of the same type in the project found by Dynamic Update.  | 
|     | RoomSeparationLinesOverlap |  Highlighted room separation lines overlap. One of them may be ignored when Revit finds room boundaries. Delete one of the lines.  | 
|     | SpaceSeparationLinesOverlap |  Highlighted space separation lines overlap. One of them may be ignored when Revit finds space boundaries. Delete one of the lines.  | 
|     | WallAreaBoundaryOverlap |  Wall and area boundary line overlap. Color fills, area tags and areas may not behave correctly.  | 
|     | WallRoomSeparationOverlap |  A wall and a room separation line overlap. One of them may be ignored when Revit finds room boundaries. Shorten or delete the room separation line to remove the overlap.  | 
|     | WallsOverlap |  Highlighted walls overlap. One of them may be ignored when Revit finds room boundaries. Use Cut Geometry to embed one wall within the other.  | 
|     | WallSpaceSeparationOverlap |  A wall and a space separation line overlap. One of them may be ignored when Revit finds space boundaries. Shorten or delete the space separation line to remove the overlap.  |
