PTREF - reference to a 3D Pointset element.

•

GMREF - reference to a 3D Geomset element.

•

PARAM - the component parameters, a list of values used in the Structural Pointset, 3D Pointset and 3D Geomset to define the Component.

•

GTYPE - a word attribute indicating the generic type of the Fitting. Any word value may be used, but the word FITT is suggested.

•

CTYA - a word attribute used only if the Fitting is attached to a pipe hanger in the Design DB. Any word value may be used. If the connection type attribute of the pipe hanger (HCON or TCON) has not been set when the Fitting is selected in the design process, the attribute will automatically be set to the value of CTYA. The AVEVA E3D™ data consistency checks (refer to Data Consistency Checking) check whether the connection type attributes of the Fitting and pipe hanger match.

DTREF - reference to a Dataset element.
