| | 393 Vector to CAD |
 | | Note that if you are converting a vector object with lines and polygons and turn on the Polygons check button, the output CAD object has only polygons ("dangling lines" inside polygons, such as those that occur when you convert a vector object of roads in an urban area, are also part of polygons). |
 | | Voronoi Polygons, also known as the Thiessen polygon network, are a derivative of the TIN and are also useful for representing two-dimensional surfaces. |
 | | Voronoi Polygon diagrams, however, cannot conform in the vertical dimension to a feature, and consequently cannot be used for meaningful interpolation of elevations, slope calculation, volume calculation, or volumetric analyses of surface morphology, minimal energy paths, or visibility. |
