8.2 2D Surface
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 PowerTopoLite then calculates contour
and 2D surface.
NOTE:
The polygon is defined by the point you select. Therefore, the order in which
you enter the point 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],
polygon is defined according to the order of your selection.
NOTE:
You have to select points in such a way that the line segments that define the polygon
do not intersect.
NOTE:
Selected points should be less than 500 points.
From the PowerTopoLite screen, press [F2][CALC]
to view the CALCULATION screen.
