Surface (data set) Create a surface data set. Syntax model.result().dataset().create(<dtag>,"Surface"); model.result().dataset(<dtag>).set(property, <value>); Description model.result().dataset().create(<dtag>,"Surface") creates a surface data set with the name <dtag>. The surface data set makes it possible to evaluate surfaces of a 3D model in 2D or 3D. For evaluation in 2D, different parameterizations of the 2D projection are available. The following properties are available: Table 7-89: Valid Property/Value Pairs for Surface Data Sets Property Value Default Description data none | data set name First compatible data set The solution data set this feature refers to. param face | xy | yz | zx | yx | zy | xz | expr face The projection used when evaluating in 2D. exprx String When param is expr: The x-axis expression when evaluating in 2D. expry String When param is expr: The y-axis expression when evaluating in 2D.
