class Lin2d from gp inherits Storable
---Purpose: Describes a line in 2D space.
-- A line is positioned in the plane with an axis (a gp_Ax2d
-- object) which gives the line its origin and 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
-- GccAna and Geom2dGcc packages which provide
-- functions for constructing lines defined by geometric
-- constraints
-- gce_MakeLin2d which provides functions for more
-- complex line constructions
-- Geom2d_Line which provides additional functions for
-- constructing lines and works, in particular, with the
-- parametric equations of lines
