You use the commands described in this section in the .ppc file to define the pre-processing of piping data in a PCF. You can use these commands to add attributes, and change, edit, or delete records so that the piping data file is imported successfully.
You can qualify most PCF commands with a WHERE statement followed by an expression. If the WHERE statement evaluates as TRUE, Isogen runs the command. You can include any of the following macros in the WHERE statement
-
$P.attribute$
-
$C.attribute$
-
$C.PCFTYPE$
-
$C.Size1$
-
$C.Size2$
-
$C.Size3$
where attribute is the name of the PCF attribute, P is the pipeline, C is the current component, and PCFTYPE is the current component type, such as flange, valve, or weld. Size1, Size2, and Size3 represent the first, second, and third bores of the component.
