There are several workbooks, Piping Specification.xls and Pipe Bending Manufacturability Rules.xls for example, that define the piping rules in the software. Rules control how you want the software to behave during certain circumstances. You should review and customize, as needed, all delivered rules based on what makes sense for your company. There are three general categories for rules:
Piping Materials Class Rules - These rules apply to specific material classes. Different rules can be defined for each material class. For more information, see Piping Materials Class Rules.
Piping Specification Rules - These rules apply to all the material classes across the project. For more information, see Piping Specification Rules.
Pipe Bending Manufacturability Rules - These rules apply to checking pipe bends for manufacturability. For more information, see Pipe Bending Data.
