Contouring
The Contour Options Dialog controls Simulator’s contouring capabilities. To access it, click the right mouse button on an empty area of the oneline and choose Contouring from the resulting local menu, or choose Contouring from the Active ribbon group on the Onelines ribbon tab.
Contouring is available in both Run Mode and Edit Mode, however when you switch from Run Mode back to Edit Mode, Simulator automatically removes the contour from the oneline diagrams. You can still choose to reapply the contour while in edit mode however.
