This class encapsulates all the properties of the slope arrow surface analysis. Slope ranges are specified % grade, where 1.00 is 100%. The color is an AutoCAD Color object. A Slope direction arrow analysis typically contains several slope arrow ranges. The Surface.Analysis.GetSlopeArrowData() method returns an array of SurfaceAnalysisSlopeArrowData objects, one for each slope arrow range.
