The oacLayerShapeAngle layer constraint specifies the allowed geometry orientations on a designated layer. This constraint uses an enumerated type to specify the allowed layer geometry orientations of:
| Constraint type: | oaLayerConstraint |
| Value types: | oaIntValue |
| Database types: | oaTech |
| Object types: | oaAppObject |
The following value types are supported by this constraint:
This oaIntValue specifies the allowed geometry orientations on the designated layer. The possible values are those of the oaShapeAngleType enum.
Units: Enum
This value is represented by an oaShapeAngleType enumeration:
| Value | Name |
|---|---|
| oacAllShapeAngleType | all |
| oacDiagonalAndOrthogonalShapeAngleType | diagonalAndOrthogonal |
| oacOrthogonalOnlyShapeAngleType | orthogonalOnly |
Some CMOS processes limit geometries on certain layers to orthogonal-only orientations. This constraint can be used to override the default allowed geometry orientation set for all layers by the oacShapeAngleConstraint.
