A relationship can be defined between the MapEnumDef and an EnumEnum in the SmartPlant schema using the MapEnumToEnum relation. Codelist values must match between the Smart 3D Catalog Schema and the SmartPlant EFSchema.
Smart 3D 2008 and higher supports mapping the codelist values. If the SPMapEnumDef is not mapped to an EnumEnum, then it assumes that the codelist values match between Smart 3D and the EFSchema. Codelist values in the delivered SP3DPublishMap.xml file do not have the mapping because they match on codelist numbers between Smart 3D and EFSchema.
