Most of the other passage-modeling modes represent the passage walls in two dimensions. This allows for a simpler and faster display. In 3D Polygon mode, a 3D prism or polygon is drawn around each shot by connecting the Left, Right, Up and Down dimensions. This creates a 3D image of the passage that can be rotated and tilted so you can see all aspects of the passage wall. You also have control of the shape of the passage outline, the rounding of corners and how the passages are joined. These options, make the passage model more realistic. Model3DOutline The main disadvantage of this mode is that it has to draw three times as many lines, so it runs slower.
