3D P-point Set (PTSET) (usually abbreviated to 3D Pointset) - a definition of the position, direction, connection type and bore of a Component’s P-points, to be used by MODEL, ISODRAFT, etc.

•

3D Geometry Set (GMSET) (usually abbreviated to 3D Geomset) - a grouping of 3D primitive elements, defining the dimensions, orientation and obstruction geometry of each primitive. Used by MODEL and the Drawing modules.

•

Data Set (DTSET) (usually abbreviated to Dataset) - a grouping of DATA elements, holding any catalogue data not stored more specifically elsewhere and which is required for use in MODEL or DRAW; e.g. the cross-sectional area of a structural steel member calculated from its parameterised dimensions.

•

Detailing Text (DTEX) - elements containing general descriptive text relating to a Component. Referred to from SPCOM elements in the Specification. For further details see Detailing Text.

•

Material Text (MTEX) - elements containing text describing the material(s) from which the physical Component is constructed. Referred to from SPCOM elements in the Specification. For further details see Material Text.
