Hi Jorge,
Some people have asked same question before, the answer is no. CAESAR II writes all the piping components information in the pcf file, and there is no statement for compass, therefore we can not draw compass in isometric drawings. The coordinate system used by isogen is not cartisian system (X-Y-Z), instead, it is based on North-west, South-east and Up-down. You can always edit the dwg/dxf file in AutoCAD and draw the compass by yourself, or have a customized backing sheet with compass located in the corner.
