====XRefPlanes====


The definition of the frame table positions in the Vessel X-direction. The authoring application must export ALL the RefPlane positions.  If more than one XRefPlanes definition is exported, the authoring application shall identify the main reference system by setting the isMainSytem=true. It is also possible to give a reversed frame system (positions are given Fore to Aft). This is specified by setting isReversed=true.
%%XRefPlanes%% has the following child elements:
