Value Type

BoolValue

When set to true, an edge on layer1 must coincide with an edge on layer2.

Optional Parameters

edgeDirection	Specifies that the constraint applies only to edges in this direction. Type: IntValue 0 any 1 horizontal 2 vertical
endOfLineOnly	Specifies that the constraint applies only if the layer1 edge is between two convex corners and its length is within the specified edgeLengthRangeArray. Type: BoolValue
edgeLengthRangeArray
	Specifies that the constraint applies only if the layer1 edge length is within this range (in user units). Type: RangeArrayValue

Examples

Specifies that horizontal Metal1 edges between two convex corners that are less than 0.02 user units in length, or greater than 0.03 user units and less than 0.04 user units in length, must coincide with a Metal2 edge.
