Syntax

public int SplitRegion(
	UV gridUV,
	RectangularGridSegmentOrientation splitDirection,
	out int newSegmentId
)

gridUV UV: Coordinates of a point in the rectangular grid of this compound structure.
splitDirection RectangularGridSegmentOrientation: Specifies the direction of the split.
newSegmentId Int32%: The id of segment that bounds both the original region and the new region.

Int32
The id of the region created by this operation.

Exception	Condition
ArgumentNullException	A non-optional argument was null
ArgumentOutOfRangeException	A value passed for an enumeration argument is not a member of that enumeration
InvalidOperationException	Split and merge regions operations can be used only for vertically compound structures without variable thickness layers.

This method is meant to be used in conjunction with FindEnclosingRegionAndSegments(UV, RectangularGridSegmentOrientation, Int32%, Int32%). Grid coordinates correspond to uv coordinates of faces.
