Input object collection that contains the geometry that defines the shape of the connector. When the specified shape is rectangular, valid input includes a single rectangular face or four linear edges on a planar face that define a rectangle. These edges do not need to connect but two of them need to be parallel to each other and perpendicular to the other two edge. For example, the picture below illustrates four valid lines and the resulting rectangle.
When the specified shape is undefined, valid input includes the input described above for a rectangular shape but also allows a circular planar face, a circular edge (it can be an arc), a planar face that has a slot shape, or four edges that define a slot or oval shape, as illustrated below.
