Automatic Level Calculating Attribute
Slope is a measure of change in elevation. It is a crucial parameter in several well-known predictive models used for environmental management. One way to express slope is as a percentage. To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run. Thus, percent slope equals (rise / run) x 100. Using this attribute you can easily get the second level as per given slope (%). Instructions ============ Simply enter the first level, required slope in percentage (%) in the attribute and adjust the poly line for the length. Regenerate your drawing 2-3 times it will automatically calculate the second level for you.
