Void

encloses a voided area of the TIN surface. the boundary <i>LineStrings</i> of the <i>Polygon</i> behave as breaklines in that triangles in the <i>PrivatePatches</i> attribute of the <i>TIN</i> value must be adjusted boundary becomes an edge of two or more triangles. However, for regular voids, only the elevations of the void boundary vertices take precedence these vertices are treated as points for triangulating. The regular void elevations from the original surface take precedence. The area bounded by TIN elements having a <i>'</i>break void', 'drape void', 'void' and 'hole' element type are still considered to be part of the TIN surface, rather than a hole bounded by an interior boundary of the surface. This distinction is significant when merging two TIN surfaces.
