详细描述

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. See Also GccAna and Geom2dGcc packages which provide functions for constructing lines defined by geometric constraints gce_MakeLin2d which provides functions for more complex line constructions Geom2d_Line which provides additional functions for constructing lines and works, in particular, with the parametric equations of lines

构造及析构函数说明

◆ GLin2d() [1/4]

GLin2d.GLin2d ( )

Creates a Line corresponding to X axis of the reference coordinate system.

◆ GLin2d() [2/4]

GLin2d.GLin2d ( GAx2d theA )

Creates a line located with theA.

◆ GLin2d() [3/4]

GLin2d.GLin2d	(	GPnt2d	theP,
		GDir2d	theV
	)

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

◆ GLin2d() [4/4]

GLin2d.GLin2d	(	double	theA,
		double	theB,
		double	theC
	)

Creates the line from the equation theA*X + theB*Y + theC = 0.0 Raises ConstructionError if Sqrt(theA*theA + theB*theB) <= Resolution from gp. Raised if Sqrt(theA*theA + theB*theB) <= Resolution from gp.

成员函数说明

◆ Angle()

double GLin2d.Angle ( GLin2d theOther )

Computes the angle between two lines in radians.

◆ Coefficients()

void GLin2d.Coefficients	(	double[]	theA,
		double[]	theB,
		double[]	theC
	)

Returns the normalized coefficients of the line : theA * X + theB * Y + theC = 0.

◆ Contains()

boolean GLin2d.Contains	(	GPnt2d	theP,
		double	theLinearTolerance
	)

Returns true if this line contains the point theP, that is, if the distance between point theP and this line is less than or equal to theLinearTolerance.

◆ Direction()

GDir2d GLin2d.Direction ( )

Returns the direction of the line.

◆ Distance() [1/2]

double GLin2d.Distance ( GLin2d theOther )

Computes the distance between two lines.

◆ Distance() [2/2]

double GLin2d.Distance ( GPnt2d theP )

Computes the distance between <me> and the point <theP>.

◆ Location()

GPnt2d GLin2d.Location ( )

Returns the location point (origin) of the line.

◆ Mirrored() [1/2]

GLin2d GLin2d.Mirrored ( GAx2d theA )

Performs the symmetrical transformation of a line with respect to an axis placement which is the axis of the symmetry.

GAx2d GLin2d.Position ( )

Returns the axis placement one axis with the same location and direction as <me>.

◆ Reversed()

GLin2d GLin2d.Reversed ( )

Reverses the positioning axis of this line. Note: - Reverse assigns the result to this line, while - Reversed creates a new one.

◆ Rotated()

GLin2d GLin2d.Rotated	(	GPnt2d	theP,
		double	theAng
	)

Rotates a line. theP is the center of the rotation. theAng is the angular value of the rotation in radians.

◆ Scaled()

GLin2d GLin2d.Scaled	(	GPnt2d	theP,

Changes the direction of the line.

◆ SetLocation()

void GLin2d.SetLocation ( GPnt2d theP )

Changes the origin of the line.

◆ SetPosition()

void GLin2d.SetPosition ( GAx2d theA )

Complete redefinition of the line. The "Location" point of <theA> is the origin of the line. The "Direction" of <theA> is the direction of the line.

◆ SquareDistance() [1/2]

double GLin2d.SquareDistance ( GLin2d theOther )

Computes the square distance between two lines.

◆ SquareDistance() [2/2]
