Elements Used in Structural Sections/Categories

A Structural Section or Category may contain all those elements listed in Elements Used in Both Types of Catalog Section/Category plus the following:

• Structural Pointset (PTSSET) - a definition of the position and direction of a Component’s P-lines, to be used by Model.

• Negative 3D Geometry Set (NGMSET) (usually abbreviated to Negative 3D Geomset) - a grouping of 3D negative primitive elements (representing holes, end preparations etc.), defining the dimensions, orientation and obstruction geometry of each primitive. Used by the Model and Draw modules.

• Structural Geometry Set (GMSSET) (usually abbreviated to Structural Geomset) - a grouping of 2D primitive elements, defining the dimensions, orientation and obstruction geometry of each primitive. Used by the Model and the Draw modules.

• Profile (PROF) - a 2D structural Component defining the cross-section of a beam, column (a Section). It consists of a list of component parameters and references to a Structural Pointset element and a Structural Geomset element. The Pointset and Geomset make use of the component parameter values in defining the size and geometry of the Component. In the design process, a length is associated with a Profile to produce a Section.

• Joint (JOIN) - a 3D structural Component defining a physical means of attaching one Section to another. It consists of a list of component parameters and references to a Structural Pointset element, a 3D Pointset element and a 3D Geomset element. The two Pointsets and the Geomset make use of the component parameter values in defining the size and geometry of the Component.

• Fitting (FITT) - a 3D structural Component defining an object which is physically attached to a Section but is not part of the structure formed by Sections and Joints. For example, a Fitting may be used to attach a pipe hanger to a Section. The element consists of a list of component parameters and references to a 3D Pointset element and a 3D Geomset element. The Pointset and Geomset make use of the component parameter values in defining the size and geometry of the Component.

The Catalog structure as described so far may be used in various ways, but the recommended method of use is to place only one type of element in each Catalog Section, and to place different kinds of Components in different Catalog Categories. For example, you might place all 3D Pointsets for Piping Components in one Piping Section and all 3D Geomsets for Piping Components in another, with separate Piping Sections for equal tees and reducing tees. When defining Profiles, you might place Profiles for Universal Beams in one Structural Section, Profiles for Unequal Angles in another, and so on.
