Line (LINE)

In addition to the three-dimensional primitive elements, 3D Geomsets may contain Line (LINE). A LINE has one particular attribute:

• PTS—a set of numbers (up to six) representing P-point numbers of the P-points in the corresponding Pointset, which determine the course of the line.

The values held in PTS are set by the SETPoints command, followed by point specifications in which each p-point identifier is preceded by ‘P’ or ‘T’, for example, P1 P2 T3 P4. When the P-point is preceded by P it is treated in the same way as a point element (POINT) in the Design Data; when preceded by a T it is treated in the same way as a tangent point element (TANP) in the Design Data. (Refer to the Design Reference Manual for further details).
