Shading Your Model
For fringe, contour, and vector result windows, use the > toggle to turn shading on and off for your model. The default for the toggle is the On state.
In most cases, the shaded view improves the overall appearance of the result window. However, for viewing flat-surface models at certain angles, you may need to turn shading off to get an accurate idea of what your plot looks like. This is because shading is based on reflected light, and a flat surface viewed straight on reflects minimal color. Thus, you do not see correct demarcation between the various legend values. When you turn shading off, the model shows demarcations correctly.
