Adding a Specification Parameter to a Fitting To add a specification parameter to a fitting with multiple configurations: In the design table, add a column with a heading using this syntax: Specification@CPointn where Specification is the name entered in Specification field name. If you typed a name other than the default (for example, Class), then use that name (for example, Class@CPointn). CPointn is the name of the connection point. If the part has multiple connection points, create a column in the design table for each connection point. Repeat steps 1 and 2 for all fittings (elbows, tees, etc.) you plan to use in the route. In the pipe or tube part you plan to use, you must add a corresponding configuration-specific custom property: $PRP@Specification (if you use the default name) or, for example, $PRP@Class (if you specified a different name).
