Port¶

, or

Type:	int
Range:	[1, 5]

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.
