Smart 3D 2008 and higher supports mapping the codelist. If the SPMapEnumListDef is not mapped to an EnumListType, then it assumes that the codelist matches between Smart 3D and the EFSchema. Codelists in the delivered SP3DPublishMap.xml file will be pre-mapped to the EFSchema.
A relationship can be defined between the MapEnumListDef and an EnumListType in the SmartPlant schema using the MapEnumListToEnumList relation if this property is to be published using this list. If this relation is not defined, the enum list value is assumed to be one-to-one.
