In OpenPlant Modeler, there are some support classes which are not mapped to their respective AutoPlant class and therefore they are exported as AT_SUPPORT in PXF file. However, there are classes which are exported on their respective classes, for example TEE_SHOE class is mapped to AT_SUPPORT_TEESHOE class and is exported correctly in PXF file. Whereas SPRING_HANGER is exported as AT_SUPPORT in PXF file as shown below.
Similarly, RISER_CLAMP is also exported as AT_SUPPORT in PXF output.
