Detailed Description

A diagram item that adds a labeled arrow to the canvas.

Note: The dimension label will not scale with the reset of the diagram. You will need to adjust the font size and possibly the DiagramBuilder's scale adjustment (see DiagramBuilder.SetScaleAdjustment()) to make the label display as desired.
