class MakeLin from gce inherits Root from gce

    ---Purpose : This class implements the following algorithms used 
    --           to create a Lin from gp.
    --           * Create a Lin parallel to another and passing 
    --             through a point.
    --           * Create a Lin passing through 2 points.
    --           * Create a lin from its axis (Ax1 from gp).
    --           * Create a lin from a point and a direction.

is

Create (A1 : Ax1 from gp)  returns MakeLin;
    --- Purpose : Creates a line located along the axis A1.


Create (P : Pnt from gp; 
    	V : Dir from gp) returns MakeLin;
    --- Purpose : 
    --  <P> is the location point (origin) of the line and
    --  <V> is the direction of the line.

Create(Lin    :     Lin from gp;
       Point  :     Pnt from gp) returns MakeLin;
    ---Purpose : Make a Lin from gp <TheLin> parallel to another 
    --           Lin <Lin> and passing through a Pnt <Point>.

Create(P1     :     Pnt from gp;
       P2     :     Pnt from gp) returns MakeLin;
    ---Purpose : Make a Lin from gp <TheLin> passing through 2 
    --           Pnt <P1>,<P2>.
    --           It returns false if <p1> and <P2> are confused.

Value(me) returns Lin from gp
    raises NotDone
    is static;
    ---C++: return const&
    --- Purpose: Returns the constructed line.
    -- Exceptions StdFail_NotDone is raised if no line is constructed.

Operator(me) returns Lin from gp
    is static;
    ---C++: return const&
