gce_MakeDir Class Reference

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

Standard_EXPORT gce_MakeDir (const gp_Vec &V)
 Normalizes the vector V and creates a direction.
Status is "NullVector" if V.Magnitude() <= Resolution.
.
Standard_EXPORT gce_MakeDir (const gp_XYZ &Coord)
 Creates a direction from a triplet of coordinates.
Status is "NullVector" if Coord.Modulus() <=
Resolution from gp.
.
Standard_EXPORT gce_MakeDir (const Standard_Real Xv, const Standard_Real Yv, const Standard_Real Zv)
 Creates a direction with its 3 cartesian coordinates.
Status is "NullVector" if Sqrt(Xv*Xv + Yv*Yv + Zv*Zv)
<= Resolution
.
Standard_EXPORT gce_MakeDir (const gp_Pnt &P1, const gp_Pnt &P2)
 Make a Dir 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:
- 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,
- the modulus of Coord,
- Sqrt(Xv*Xv + Yv*Yv + Zv*Zv).
.
Standard_EXPORT const gp_Dir & Value () const
 Returns the constructed unit vector.
Exceptions StdFail_NotDone if no unit vector is constructed.
.
Standard_EXPORT const gp_Dir & Operator () const
Standard_EXPORT operator gp_Dir () const
