Inherits Operation.
Converts a two-dimensional grid to a three-dimensional Workspace MeshModel surface using a marching squares algorithm. If only the 'Base grid' is given, the output is a three-dimensional surface of the base grid elevation. If a 'Base grid' and a 'Height grid' is given, the output is a three dimensional surface of the height plus the base cut around a elevation contour given by the value of 'Height cut-off'. If a 'scalar grid' is given and extra node state 'scalar' is created using interpolated values of the scalar grid. Similarly, if x and y 'vector grid' components are given, and extra node state 'vmag' is created using interpolated values of the magnitude of the vector components. If 'Create contour only' is selected only contour line segments are output."
