The Support Selection Rule (SSR) helps you place appropriate supports in a model by providing a sorted list of possible supports in the Type box. You must check the Rule box on the ribbon to enable this command.
For example, you can define the sort order in IJUAHgrRulePriority ::Rule Priority of the Assy_RR_DR_LS page of the HS_Assembly.xls spreadsheet. If you do not specify a sort order, then the list of assemblies is sorted alphabetically based on PartDescription.
Creating an Assembly
You create an assembly from a feature (pipe, HVAC duct, or cable tray) and a structure in the model. Then, the software compares the support properties stored in the catalog with your assembly and returns a set of appropriate supports in the Type box on the ribbon.
