Leader Dimension (Polygonal Line)

The Leader Dimension (Polygonal Line) command allows you to add polygonal leader dimension lines in Footprint Editor. It is executed by clicking Home > Dimension > Add split button Polygonal Line, or Draw > Dimension Line > Polygonal Line on the ribbon. The dimension is added to the user-defined layer that you select in the displayed Leader Dimension (Polygonal Line) dialog. You can change the properties of the dimension line by selecting it on the canvas, and then editing the settings in the Properties panel. To change the dimension value and the position of the dimension line, set Edit dimension to ON, and then drag the dimension line on the canvas. This command is only available in 2D View mode.
