Value Type

keepAlignedShapes constraints have a BoolValue. When set to true, coincident edges of shapes on both layers must remain coincident. The length of the shared edge can change as long as the shapes maintain at least one shared point on the shared edge.

Parameter

• alignmentType (IntValue, optional) specifies the alignment of the shapes as one of the following:
  

  Value	Alignment
  0	The coincident edges of the shape on one layer must be inside of the shape on the second layer.
  1	The coincident edges of the shape on one layer must be outside of the shape on the second layer.
  2	The coincident edges of the shape on one layer must be either inside or outside of the shape on the second layer.

The length of the shared edge can change as long as the shapes maintain at least one shared point on the shared edge.
