Computes the coplanar intersection of two objects.

**Namespace:**
ceometric.VectorGeometry

**Assembly:**
ceometric.VectorGeometry (in ceometric.VectorGeometry.dll) Version: 1.8.0.0 (1.8.0.0)

# Syntax

C# |

public PointSet Intersect2d( Line line ) |

Visual Basic (Declaration) |
---|

Public Function Intersect2d ( _ line As Line _ ) As PointSet |

Visual C++ |
---|

public: PointSet^ Intersect2d( Line^ line ) |

#### Parameters

- line
- Type: ceometric.VectorGeometry..::.Line

An intersecting Line coplanar to the ellipse.

#### Return Value

Returns a PointSet containing the intersection points of the circumference of the ellipse and line. This point set contains- 0 intersection points if the ellipse is coplanar to line but does not intersect line
- 1 intersection point if the ellipse is coplanar to line and line is tangent to the ellipse
- 2 intersection points if the ellipse is coplanar to line and line crosses the ellipse

Returns null if the objects are not coplanar.

# Remarks

Use Intersect3d(Line) for non-coplanar intersection.
