gce_MakeDir2d Class Reference

This class implements the following algorithms used
to create a Dir2d from gp.
* Create a Dir2d with 2 points.
* Create a Dir2d with a Vec2d.
* Create a Dir2d with a XY from gp.
* Create a Dir2d with a 2 Reals (Coordinates).

 gce_MakeDir2d (const gp_Vec2d &V)
 Normalizes the vector V and creates a direction.
Status is "NullVector" if V.Magnitude() <= Resolution.

 gce_MakeDir2d (const gp_XY &Coord)
 Creates a direction from a triplet of coordinates.
Status is "NullVector" if Coord.Modulus() <=
Resolution from gp.

 gce_MakeDir2d (const Standard_Real Xv, const Standard_Real Yv)
 Creates a direction with its 3 cartesian coordinates.
Status is "NullVector" if Sqrt(Xv*Xv + Yv*Yv )
<= Resolution

 gce_MakeDir2d (const gp_Pnt2d &P1, const gp_Pnt2d &P2)
 Make a Dir2d from gp <TheDir> passing through 2
Pnt <P1>,<P2>.
Status is "ConfusedPoints" if <P1> and <P2> are confused.
Warning
If an error occurs (that is, when IsDone returns
false), the Status function returns:

const gp_Dir2dValue () const
 Returns the constructed unit vector.
Exceptions StdFail_NotDone if no unit vector is constructed.

const gp_Dir2dOperator () const
 operator gp_Dir2d () const

  • gce_ConfusedPoints if points P1 and P2 are coincident, or
  • gce_NullVector if one of the following is less
    than or equal to gp::Resolution():
    • the magnitude of vector V,
