A Box has 8 point-Ports (globally oriented) at its vertices numbered counterclockwise starting on the bottom facet. Further, a box has a Center port which coincides with its center of mass and a BottomCenter port at the center of the bottom facet. The default port is Point1.

Number	Name	Position	Type	Coordinate System
1	Point1	$p_1=[0, 0, 0]$	point	$x'=[1, 0, 0], y'=[0, 1, 0], z'=[0, 0, 1]$
2	Point2	$p_2=[l, 0, 0]$	point	$x'=[1, 0, 0], y'=[0, 1, 0], z'=[0, 0, 1]$
3	Point3	$p_3=[l, w, 0]$	point	$x'=[1, 0, 0], y'=[0, 1, 0], z'=[0, 0, 1]$
4	Point4	$p_4=[0, w, 0]$	point	$x'=[1, 0, 0], y'=[0, 1, 0], z'=[0, 0, 1]$
5	Point5	$p_5=[0, 0, h]$	point	$x'=[1, 0, 0], y'=[0, 1, 0], z'=[0, 0, 1]$
6	Point6	$p_6=[l, 0, h]$	point	$x'=[1, 0, 0], y'=[0, 1, 0], z'=[0, 0, 1]$
7	Point7	$p_7=[l, w, h]$	point	$x'=[1, 0, 0], y'=[0, 1, 0], z'=[0, 0, 1]$
8	Point8	$p_8=[0, w, h]$	point	$x'=[1, 0, 0], y'=[0, 1, 0], z'=[0, 0, 1]$
9	Center	$(p_1+p_7)/2=[\tfrac{l}{2}, \tfrac{w}{2},\tfrac{h}{2}]$	point	$x'=[1, 0, 0], y'=[0, 1, 0], z'=[0, 0, 1]$
10	BottomCenter	$(p_1+p_3)/2=[\tfrac{l}{2}, \tfrac{w}{2},0]$	point	$x'=[1, 0, 0], y'=[0, 1, 0], z'=[0, 0, 1]$

Here, $l,w,h$ refer to Length, Width and Height.
