Orca3D Version 2: The OrcaCreateFloatPlane command

New with Orca3D version 2: The OrcaCreateFloatPlane command. Allows the user to define a plane (representing a measured flotation plane) from one, two, or three freeboard or draft measurements. For each measurement, the command requests input of the reference location of the measurement (such as a transom corner or deck location where the measurement was made from) and the measurement to the water surface. If only one point is specified, the flotation plane is assumed to be a zero trim/zero heel plane. If two points are specified, the plane is assumed to be either zero trim or zero heel depending on the relationship of the first and second reference points. Finally, if three measurement points are specified a general plane with heel and trim is created. The resulting plane is added to the Rhino model so that it can be used as input to a hydrostatics calculation. The OrcaHydrostatics command now allows the flotation plane to be defined with a planar surface, and the corresponding sinkage, trim, and heel are automatically computed and used for the hydrostatics calculation.
