The Edge object represents an edge in a geometry model. It is derived from the Shape object and inherits all its methods and properties. In
addition the Edge object offers some properties specific to the edge. All these
properties are read-only.
Returns the Block (if any) that is adjacent to the edge from the right side as Block.
Please note, that the Start, End, Left and Right properties are
relative to the edge intrinsic direction, which is always counterclockwise for arcs and is
determined for line segments by the order of pointing vertices when the edge was created.
