          <desc>Bit mask of CNAT values which determine which directions to check. If not specified, defaults to the vertices own CNAT mode, i.e. usually the one specified in VertexCNAT in the definition DefCore.txt file. If the vertex does not have any CNAT value, no direction is checked.</desc>

    <desc>Determines on which side individual or all vertices of an object are touching the landscape. Directions are specified using <emlink href="definition/cnat.html">CNAT values</emlink>.</desc>
