minInnerVertexClearance

Specifies the minimum spacing between the inside corner of a shape on layer1 and a shape on layer2. The minimum spacing is satisfied when at least one of the layer2 shape edges that are adjacent to the inside corner edges of the layer1 shape meets the required spacing.

Optionally, this constraint does not apply if both edges of the layer2 shape, which are adjacent to the layer1 inside corner are at a distance greater than or equal to the specified distance.

minInnerVertexClearance Quick Reference

Value Type

minInnerVertexClearance constraints have a Value that represents the minimum clearance.

Parameters

• distance (Value, optional) specifies that the constraint does not apply if both layer2 edges adjacent to the inside corner are greater than or equal to this distance from the layer1 shape that forms the inside corner.

Examples

In this example, when NW forms an inside corner, then at least one adjacent OD edge must have a 1.0 clearance, or both OD edges must have clearance of 0.5 user units. All OD edges must have a clearance of at least a 0.3 user units from NW shapes.
