Describes a line in 3D space. A line is positioned in space with an axis (a gp_Ax1 object) which gives it an origin and a unit vector. A line and an axis are similar objects, thus, we can convert one into the other. A line provides direct access to the majority of the edit and query functions available on its positioning axis. In addition, however, a line has specific functions for computing distances and positions. See Also gce_MakeLin which provides functions for more complex line constructions Geom_Line which provides additional functions for constructing lines and works, in particular, with the parametric equations of lines.
