`Enums.SurfacePlacementDrapedFlat`	`(4)` The feature is draped to the surface by ignoring the Z-Value. Symbols will appear flat on the surface. New value since 100.7. In the case of a ModelSceneSymbol, there is no difference in behavior between SurfacePlacementDrapedFlat and SurfacePlacementDrapedBillboarded.
