ICircle2d_DG Interface

If this circle defines an edge or otherwise is part of a model, after any modification IGeometry_DG.SetModified() has to be called for the change to appear in 3D view.

A standalone 2D circle can be created via IObjectGenerator_DG.Create("ICircle2d_DG") > ICircle2d_DG query.

Implements also: ICurve2d_DG, IGeometricObject_DG, IObject_DG.

void Init(DG2D center, double radius)


void Init1(DG2D center, DG2D axisX, double radius)

The axisX parameter defines direction in which the first point (with parameter which is the lower limit of the range) is located.


void Init2(IFrame2d_DG frame, double radius)

The frame parameter defines location of the center. The x axis of the frame defines direction in which the first point used in defining parametrisation is located.


void Init3(DG2D point0, DG2D point1, double radius)

Defines this so the points are incident.


void Init4(DG2D point0, DG2D point1, DG2D point2)

Defines this so the points are incident.

void SetRadius(double radius)


DG2D GetCenter()


void SetCenter(DG2D center)


IFrame2d_DG GetLocation()

The returnel frame is by value. Its modifications are copied to the curcle only inside a SetLocation() call below


void SetLocation(IFrame2d_DG frame)

Modifies location and orientation of the circle
