Description:
Merges the two regions which share the specified segment.

public int MergeRegionsAdjacentToSegment(
	int segmentId,
	int layerIdxForMergedRegion
)

Public Function MergeRegionsAdjacentToSegment ( _
	segmentId As Integer, _
	layerIdxForMergedRegion As Integer _
) As Integer

public:
int MergeRegionsAdjacentToSegment(
	int segmentId, 
	int layerIdxForMergedRegion
)

Int32

segmentId

The id of a segment in the underlying grid.
Int32

layerIdxForMergedRegion

The index of the layer to which the resulting region will be associated.

Return Value int The id of the resulting region. If -1 is returned, then the operation would have produced an invalid region and was not performed.

Autodesk.Revit.Exceptions.ArgumentOutOfRangeException

The layer index is out of range.
Autodesk.Revit.Exceptions.InvalidOperationException

Split and merge regions operations can be used only for vertically compound structures without variable thickness layers. -or- The segment is not shared by adjacent regions.
