	UV gridUV,
	RectangularGridSegmentOrientation splitDirection,
	out int segmentId1,
	out int segmentId2
)
Visual Basic
Public Function FindEnclosingRegionAndSegments ( _
	gridUV As UV, _
	splitDirection As RectangularGridSegmentOrientation, _
	<OutAttribute> ByRef segmentId1 As Integer, _
	<OutAttribute> ByRef segmentId2 As Integer _
) As Integer
Visual C++
public:
int FindEnclosingRegionAndSegments(
	UV^ gridUV, 
	RectangularGridSegmentOrientation splitDirection, 
	[OutAttribute] int% segmentId1, 
	[OutAttribute] int% segmentId2
)

Parameters

gridUV
Type: Autodesk.Revit.DB..::..UV
Coordinates of a point in the rectangular grid of this compound structure.
splitDirection
Type: Autodesk.Revit.DB..::..RectangularGridSegmentOrientation
Specifies the direction of the split.
segmentId1
Type: System..::..Int32%
The id of a segment in the boundary of the containing region which is split by a line through gridUV in the specified direction.
segmentId2
Type: System..::..Int32%
The id of a segment in the boundary of the containing region which is split by a line through gridUV in the specified direction.

Return Value

Returns the id of the enclosing region, and -1 if no region encloses the point.

Remarks

Grid coordinates correspond to uv coordinates of faces.
