Color By Elevation

When polylines are on different heights in your drawing they have various elevations. For instance, if you have a drawing of a mountainous site you might have the height lines of those mountains on the appropriate height. In that case you can use the 'Color By Elevation' command to color those height lines based on their height. All you have to do is select the polylines after which you select the colors you want to apply. You select the colors by selecting an entity in your drawing that's colored with the desired color. The first color is for the lowest polylines in the drawing, the second color for the highest. Every polyline in between will be colored with mix of the two colors you selected, creating a gradient from the lowest polyline to the highest. That way you can read the height difference even in top view.
