Sets the active port for global or local positioning.

An elliptic ring has the following ports (default Port is Center).

EllipticRing Ports
Number Name Position Type Coordinate System
1 South [0, -r_2] tangential x'=[1, 0], y'=[0, 1]
2 East [r_1, 0] tangential x'=[0, 1], y'=[-1, 0]
3 North [0, r_2] tangential x'=[-1, 0], y'=[0, -1]
4 West [-r_1, 0] tangential x'=[0, -1], y'=[1, 0]
5 Center [0, 0] point x'=[1, 0], y'=[0, 1]

where r_1 is equal to RadiusX plus half the LineWidth and r_2 is equal to RadiusY plus half the LineWidth.
