Fittings and Panel Fittings

A Fitting (FITT) element allows the user to indicate a connected implied load, such as a pipe hanger attachment, or an ancillary item related to, but not an inherent part of, the structure, such as a web stiffener or a flange plate.

A Fitting is owned by a Section (SCTN) and is positioned along the Neutral Axis of the SCTN at a point defined by the Z-axis Distance (ZDIST) attribute (in the same way as for a SNOD). The Fitting may be geometrically modelled in the Catalog, and selected from the Catalog, in a similar way to a Joint, as described in Creating and Positioning Joints.

A Panel Fitting (PFIT) element serves a similar function to a FITT, but is owned by a Panel and positioned relative to the Panel’s origin. A Cofitting (COFI) element is used where a fitting spans the junction between two or more Panels. In the latter case, one of the Panels owns a PFIT while the others each own a COFI. Each COFI has its Panel Fitting Reference (PFRE) attribute set to point to the associated PFIT; the PFIT has its Cofitting Reference Array (CFRA) attribute set to point to the COFIs.
