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
