IKO_gp_Lin2d Interface
Describes a line in 2D space.
A line is positioned in the plane with an axis (a gp_Ax2d
object) which gives the line its origin and unit vector. A
line and an axis are similar objects, thus, we can convert
one into the other.
A line provides direct access to the majority of the edit
and query functions available on its positioning axis. In
addition, however, a line has specific functions for
computing distances and positions.

functions for constructing lines defined by geometric

complex line constructions

constructing lines and works, in particular, with the
parametric equations of lines

HRESULT Init()
Creates a Line corresponding to X axis of the
reference coordinate system.
HRESULT Init1(IKO_gp_Ax2d* A)
Creates a line located with A.
HRESULT Init2(KC2D* P, KC2D* V)
P is the location point (origin) of the line and
V is the direction of the line.
HRESULT Init3(double A, double B, double C)
HRESULT Reverse()
HRESULT Reversed(IKO_gp_Lin2d** ret)
Reverses the positioning axis of this line.
Note:
- Reverse assigns the result to this line, while
- Reversed creates a new one.
HRESULT SetDirection(KC2D* V)
Changes the direction of the line.
HRESULT SetLocation(KC2D* P)
Changes the origin of the line.
HRESULT SetPosition(IKO_gp_Ax2d* A)
Complete redefinition of the line.
The "Location" point of A is the origin of the line.
The "Direction" of A is the direction of the line.
HRESULT Coefficients(double* A, double* B, double* C)
Returns the normalized coefficients of the line :
A * X + B * Y + C = 0.
HRESULT Direction(KC2D* ret)
Returns the direction of the line.
HRESULT Location(KC2D* ret)
Returns the location point (origin) of the line.
HRESULT Position(IKO_gp_Ax2d** ret)
Returns the axis placement one axis whith the same
location and direction as me.
HRESULT Angle(IKO_gp_Lin2d* Other, double* ret)
Computes the angle between two lines in radians.
HRESULT Contains(KC2D* P, double LinearTolerance, VARIANT_BOOL* ret)
Returns true if this line contains the point P, that is, if the
distance between point P and this line is less than or
equal to LinearTolerance.
HRESULT Distance(KC2D* P, double* ret)
Computes the distance between this and the point P.
HRESULT Distance1(IKO_gp_Lin2d* Other, double* ret)
Computes the distance between this and the point P.
HRESULT SquareDistance(KC2D* P, double* ret)
Computes the square distance between this and the point
P.
HRESULT SquareDistance1(IKO_gp_Lin2d* Other, double* ret)
Computes the square distance between this and the point
P.
HRESULT Normal(KC2D* P, IKO_gp_Lin2d** ret)
Computes the line normal to the direction of me,
passing through the point P.
HRESULT Mirror(KC2D* P)
HRESULT Mirrored(KC2D* P, IKO_gp_Lin2d** ret)
HRESULT Mirror1(IKO_gp_Ax2d* A)

HRESULT Rotate(KC2D* P, double Ang)
HRESULT Rotated(KC2D* P, double Ang, IKO_gp_Lin2d** ret)
Rotates a line. P is the center of the rotation.
Ang is the angular value of the rotation in radians.
HRESULT Scale(KC2D* P, double S)
HRESULT Scaled(KC2D* P, double S, IKO_gp_Lin2d** ret)
Scales a line. S is the scaling value. Only the
origin of the line is modified.
HRESULT Transform(IKO_gp_Trsf2d* T)
HRESULT Transformed(IKO_gp_Trsf2d* T, IKO_gp_Lin2d** ret)
Transforms a line with the transformation T from class Trsf2d.
HRESULT Translate(KC2D* V)
HRESULT Translated(KC2D* V, IKO_gp_Lin2d** ret)

The magnitude of the translation is the vector's magnitude.
HRESULT Translate1(KC2D* P1, KC2D* P2)
HRESULT Translated1(KC2D* P1, KC2D* P2, IKO_gp_Lin2d** ret)
Translates a line from the point P1 to the point P2.
