Describes an axis in the plane (2D space). An axis is defined by:  its origin (also referred to as its "Location point"), and  its unit vector (referred to as its "Direction"). An axis implicitly defines a direct, righthanded coordinate system in 2D space by:  its origin,  its "Direction" (giving the "X Direction" of the coordinate system), and  the unit vector normal to "Direction" (positive angle measured in the trigonometric sense). An axis is used:  to describe 2D geometric entities (for example, the axis which defines angular coordinates on a circle). It serves for the same purpose as the STEP function "axis placement one axis", or  to define geometric transformations (axis of symmetry, axis of rotation, and so on). Note: to define a lefthanded 2D coordinate system, use gp_Ax22d.
GAx2d.GAx2d  (  ) 
Creates an axis object representing X axis of the reference coordinate system.
Creates an Ax2d. <theP> is the "Location" point of the axis placement and theV is the "Direction" of the axis placement.
double GAx2d.Angle  (  GAx2d  theOther  ) 
Computes the angle, in radians, between this axis and the axis theOther. The value of the angle is between Pi and Pi.
GDir2d GAx2d.Direction  (  ) 
Returns the direction of <me>.
boolean GAx2d.IsCoaxial  (  GAx2d  Other, 
double  AngularTolerance,  
double  LinearTolerance ) 
Returns True if : . the angle between <me> and <Other> is lower or equal to <AngularTolerance> and . the distance between <me>.Location() and <Other> is lower or equal to <LinearTolerance> and . the distance between <Other>.Location() and <me> is lower or equal to LinearTolerance.
boolean GAx2d.IsNormal  (  GAx2d  theOther, 
double  theAngularTolerance ) 
Returns true if this axis and the axis theOther are normal to each other. That is, if the angle between the two axes is equal to Pi/2 or Pi/2. Note: the tolerance criterion is given by theAngularTolerance.
boolean GAx2d.IsOpposite  (  GAx2d  theOther, 
double  theAngularTolerance ) 
Returns true if this axis and the axis theOther are parallel, and have opposite orientations. That is, if the angle between the two axes is equal to Pi or Pi. Note: the tolerance criterion is given by theAngularTolerance.
boolean GAx2d.IsParallel  (  GAx2d  theOther, 
double  theAngularTolerance ) 
Returns true if this axis and the axis theOther are parallel, and have either the same or opposite orientations. That is, if the angle between the two axes is equal to 0, Pi or Pi. Note: the tolerance criterion is given by theAngularTolerance.
GPnt2d GAx2d.Location  (  ) 
Returns the origin of <me>.
Performs the symmetrical transformation of an axis placement with respect to an axis placement which is the axis of the symmetry.
Performs the symmetrical transformation of an axis placement with respect to the point P which is the center of the symmetry.
void GAx2d.Reverse  (  ) 
Reverses the direction of <me> and assigns the result to this axis.
GAx2d GAx2d.Reversed  (  ) 
Computes a new axis placement with a direction opposite to the direction of <me>.
Rotates an axis placement. <theP> is the center of the rotation. theAng is the angular value of the rotation in radians.
Applies a scaling transformation on the axis placement. The "Location" point of the axisplacement is modified. The "Direction" is reversed if the scale is negative.
void GAx2d.SetDirection  (  GDir2d  theV  ) 
Changes the direction of <me>.
void GAx2d.SetLocation  (  GPnt2d  theP  ) 
Changes the "Location" point (origin) of <me>.
Translates an axis placement from the point theP1 to the point theP2.
