Data Structures

class Geom2d_Line

Describes an infinite line in the plane (2D space).
A line is defined and positioned in the plane with an
axis (gp_Ax2d object) which gives it an origin and a unit vector.
The Geom2d_Line line is parameterized as follows:
P (U) = O + U*Dir
where:

P is the point of parameter U,
O is the origin and Dir the unit vector of its positioning axis.
The parameter range is ] -infinite, +infinite [.
The orientation of the line is given by the unit vector
of its positioning axis.
