The following requirements apply to shape gaskets, i.e. the components which are inserted between shape pipes and shape components which have defined Shape Component with Gasket End Treatment (ET=1004).
For shape gasket, there is just a single CO_ORDS coordinate system and CO_ORDS_AXIS required.
Orientation and position of the coordinate system and axis must correspond to the OUTPUT_POINT coordinate system and axis of the shape pipe/component end to which the gasket should be attached to.
Shape gaskets are inserted so that the CO_ORDS coordinate system orientation and position matches the orientation and position of the OUTPUT_POINT (with ET=1004) coordinate system of the adjacent shape pipe/component.
To get proper results, the origin of the coordinate system should be positioned at half the thickness of the gasket.
