This function calculates the 2D and 3D contour of a polygon and the 2D surface of the area defined by the polygon.
You define the polygon by selecting points and PowerTopoExpress 2 then calculates contour
and 2D surface.
NOTE:
1. The polygon is defined by the points you select. Therefore, the order in which you enter the points is important.
If you select points by [ALL] or [FROM] [TO], the polygon is defined according to the order of the memory address. If you select points one by one by [ENT], the polygon is defined according to the order of your selection.
2. You have to select points in such a way that the line segments that define the polygon do not intersect.
3. Selected points should be less than 500 points.
