Standard_EXPORT Handle_Standard_Type& gp_Lin2d_Type_();

//! Describes a line in 2D space. <br>
//! A line is positioned in the plane with an axis (a gp_Ax2d <br>
//! object) which gives the line its origin and unit vector. A <br>
//! line and an axis are similar objects, thus, we can convert <br>
//! one into the other. <br>
//! A line provides direct access to the majority of the edit <br>
//! and query functions available on its positioning axis. In <br>
//! addition, however, a line has specific functions for <br>
//! computing distances and positions. <br>
//! See Also <br>
//! GccAna and Geom2dGcc packages which provide <br>
//! functions for constructing lines defined by geometric <br>
//! constraints <br>
//! gce_MakeLin2d which provides functions for more <br>
//! complex line constructions <br>
//! Geom2d_Line which provides additional functions for <br>
//! constructing lines and works, in particular, with the <br>
//! parametric equations of lines <br>
