How the various components drawn are depicted can be set in the preferences section. Each surface can be assigned to a particular preference. The first part of this preferences section applies mainly to the "Drawing" interface. It should be noted that "Color by Scale means" applies only to lines and not to text. The

Color by Scale means | Color By Elevation | Used to draw the elements in a different color depending on elevation. Color ranges must be set. If an elevation falls outside the listed ranges, the element will not be drawn. |
Automatic | When "automatic" is checked, the software calculates the difference is elevation, divides it into fifths, and assigns a color to each level. | |
Color By Slope | When this option is checked, a slope percentage must be defined for each color available. No negatives. | |
