This chapter illustrates how piping components are normally represented on isometrics. The symbols for components are specified by the SKEY attribute of each component type when it is defined in the Catalogue database. You can define different symbols if required, as described in Catalogue Requirements - Symbol Keys.
The symbols are shown in Symbol Keys of the Isodraft Reference Manual. This chapter mainly discusses how the symbols are annotated.
