Polygon Mode presents a simplified image of the passage walls. It shows the passage walls as simple straight lines connecting the left, right, up and down measurements at each station. In this mode, the passage models are strictly two-dimensional. For example, in plan mode, the left and right dimensions are connected together. In profile mode, the up and down dimensions are connected together. There is also a cross bar at each station, which forms a four-sided polygon around each shot. The main advantage of Polygon Mode is that it is much faster than the other more complex passage modeling modes.
