Detailed Description

This class implements the following algorithms used to create Lin2d from gp.

• Create a Lin2d parallel to another and passing through a point.
• Create a Lin2d parallel to another at the distance Dist.
• Create a Lin2d passing through 2 points.
• Create a Lin2d from its axis (Ax1 from gp).
• Create a Lin2d from a point and a direction.
• Create a Lin2d from its equation.

Constructor & Destructor Documentation

gce_MakeLin2d() [1/6]

gce_MakeLin2d::gce_MakeLin2d

(

const gp_Ax2d &

A

)

Creates a line located with A.

gce_MakeLin2d() [2/6]

gce_MakeLin2d::gce_MakeLin2d	(	const gp_Pnt2d &	P,
		const gp_Dir2d &	V )

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

gce_MakeLin2d() [3/6]

gce_MakeLin2d::gce_MakeLin2d	(	const Standard_Real	A,
		const Standard_Real	B,
		const Standard_Real	C )

Creates the line from the equation A*X + B*Y + C = 0.0 the status is "NullAxis"if Sqrt(A*A + B*B) <= Resolution from gp.

gce_MakeLin2d() [4/6]

gce_MakeLin2d::gce_MakeLin2d	(	const gp_Lin2d &	Lin,
		const Standard_Real	Dist )

Make a Lin2d from gp <TheLin> parallel to another Lin2d <Lin> at a distance <Dist>. If Dist is greater than zero the result is on the right of the Line <Lin>, else the result is on the left of the Line <Lin>.

gce_MakeLin2d() [5/6]

gce_MakeLin2d::gce_MakeLin2d	(	const gp_Lin2d &	Lin,
		const gp_Pnt2d &	Point )

Make a Lin2d from gp <TheLin> parallel to another Lin2d <Lin> and passing through a Pnt2d <Point>.

gce_MakeLin2d() [6/6]

gce_MakeLin2d::gce_MakeLin2d	(	const gp_Pnt2d &	P1,
		const gp_Pnt2d &	P2 )

Make a Lin2d from gp <TheLin> passing through 2 Pnt2d <P1>,<P2>. It returns false if <P1> and <P2> are confused. Warning If an error occurs (that is, when IsDone returns false), the Status function returns:

• gce_NullAxis if Sqrt(A*A + B*B) is less than or equal to gp::Resolution(), or
• gce_ConfusedPoints if points P1 and P2 are coincident.
