Description

The operator get_surface_model_paramget_surface_model_paramGetSurfaceModelParamGetSurfaceModelParamGetSurfaceModelParamget_surface_model_param returns parameters and properties of the surface model SurfaceModelIDSurfaceModelIDSurfaceModelIDSurfaceModelIDsurfaceModelIDsurface_model_id. The surface model must have been created by create_surface_modelcreate_surface_modelCreateSurfaceModelCreateSurfaceModelCreateSurfaceModelcreate_surface_model or read_surface_modelread_surface_modelReadSurfaceModelReadSurfaceModelReadSurfaceModelread_surface_model. The names of the desired properties are passed in the generic parameter GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name, the corresponding values are returned in GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value.
