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