| ArgumentException | When setting this property: A valid point must not be father then 10 miles (approx. 16 km) from the origin. -or- When setting this property: An arc leader may not have its Elbow point placed at the current position of the leader's Anchor or End point. |
| ArgumentNullException | When setting this property: A non-optional argument was null |
| InvalidOperationException | When setting this property: The leader is not currently owned by a valid element. A probable reason for that could be if the element has been independently deleted, or the leader has never been properly initialized. |
Remarks This is the mid-point of the leader and its purpose depends on the shape of the leader. For arc-shaped leaders it defines the radius of the arc. For a kinked leader it divides the leader line and shoulder line.
Note that straight-line leaders do not have an actual elbow; however, the value can still be obtained, although it will always equal the current anchor point. Consequently, an elbow point can be set even on a straight-line leader, but doing so will automatically change the leader's shape property.
It is allowed to set the Elbow point of a kinked leader to equal either the end point or anchor point of the leader. Doing so will effectively change the leader's shape to a straight line. However, the elbow of an arc leader is never allowed to be placed on either the end or anchor point.
