Basic Annotation

Structural elements, like other Design elements, can be labelled, dimensioned and used in 2D drafting. Positions and directions in the Design World must be obtained for these elements.

Annotation elements which (can) require a 3D position include labels (GLAB, SLAB); View Notes (VNOT), drafting primitives whose drafting point references (PTRF or PTFA) use a PPPT (drafting point with design data); Angular Dimension elements (ADIM) and two types of dimension points: DPPT and DPBA. Dimension points of type DPBA do not require p-line data since they are concerned with the limits of a Design element.

Annotation elements that require a 3D direction include Linear dimension elements (LDIM) and Dimension Points of type APPT. In addition, where the direction of a p-line is used for position on a Label or View Note, it can also be used to define the angle of the Label or View Note to the horizontal in the view region.

Fittings, Nodes and Joints with p-points are treated in the same way as other elements. There is no change in the functionality for annotating these.
