IgesLineEntity Class Reference

Detailed Description

IGES 110 : Line.

Spec : IGES 5.3 page 119

A line is a bounded, connected portion of a straight line which has distinct start and terminate points. A line is defined by its end points. Each end point is specified relative to definition space by triple coordinates. With respect to definition space, a direction is associated with the line by considering the start point to be listed first and the terminate point second.

The direction of the line with respect to model space is determined by the original direction of the line within definition space, in conjunction with the action of the transformation matrix on the line.
