When using the power line tools in TerraScan the activated power line may obstruct the view. In the TerraScan -> Settings -> Powerlines -> Active Line setting you have the option that controls the highlight of the active line in the display. There are three options: No hilite, Vertices, and Line Segments. Line segments is the default option. It is recommended to modify this setting to be “Vertices” such that only the vertices of the active power line segment are highlighted.
