Haul Path lines display as annotation in Edit Mode after the Balance Regions have been calculated. To display the Balance Regions in Edit Mode, choose the Design Surface and the Balance Regions layer. Zoom into the Balance Region. Change the layer to Annotation Lines and select the Haul Path line.
The selected line shows a diamond at one end. This is the "from" direction, or start of the haul. The other end of the line represents the "to", or end or the haul.
