<cxn> (Shape Connection Site)

This element specifies the existence of a connection site on a custom shape. A connection site allows a <cxnSp> to be attached to this shape. This connection will be maintined when the shape is repositioned within the document. It should be noted that this connection is placed within the shape bounding box using the transform coordinate system which is also called the shape coordinate system, as it encompasses the entire shape. The width and height for this coordinate system are specified within the <ext> transform element.

Attributes

Description

<ang> (Connection Site Angle)

Specifies the incoming connector angle. This angle is the angle around the connection site that an incoming connector will try to be routed to. This allows connectors to know where the shape is in relation to the connection site and route connectors so as to avoid any overlap with the shape.
