DEFINE_STANDARD_ALLOC gce_MakeLin2d (const gp_Ax2d &A)
 Creates a line located with A.

 gce_MakeLin2d (const gp_Pnt2d &P, const gp_Dir2d &V)
 gce_MakeLin2d (const Standard_Real A, const Standard_Real B, const Standard_Real C)
 Creates the line from the equation A*X + B*Y + C = 0.0
the status is "NullAxis"if Sqrt(A*A + B*B) <= Resolution from gp.

 gce_MakeLin2d (const gp_Lin2d &Lin, const Standard_Real Dist)
 Make a Lin2d from gp <TheLin> parallel to another
Lin2d <Lin> at a distance <Dist>.
If Dist is greater than zero the result is on the
right of the Line <Lin>, else the result is on the
left of the Line <Lin>.

 gce_MakeLin2d (const gp_Lin2d &Lin, const gp_Pnt2d &Point)
 Make a Lin2d from gp <TheLin> parallel to another
Lin2d <Lin> and passing through a Pnt2d <Point>.

 gce_MakeLin2d (const gp_Pnt2d &P1, const gp_Pnt2d &P2)
 Make a Lin2d from gp <TheLin> passing through 2
Pnt2d <P1>,<P2>.
It returns false if <P1> and <P2> are confused.
Warning
If an error occurs (that is, when IsDone returns
false), the Status function returns:

gp_Lin2d Value () const
 Returns the constructed line.
Exceptions StdFail_NotDone if no line is constructed.

gp_Lin2d Operator () const
 operator gp_Lin2d () const

Detailed Description


Constructor & Destructor Documentation

is the location point (origin) of the line and
<V> is the direction of the line.

  • gce_NullAxis if Sqrt(A*A + B*B) is less
    than or equal to gp::Resolution(), or
  • gce_ConfusedPoints if points P1 and P2 are coincident.
