# 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

A line coplanar to the triangle.

#### Return Value

Returns a PointSet containing the intersection points of the circumference of the triangle and line. This point set contains- 0 intersection points if the triangle is coplanar to line but does not intersect line
- 1 intersection point if the triangle is coplanar to line and touches line with a vertex
- 2 intersection points if the triangle is coplanar to line and line crosses two edges of the triangle
- 2 intersection points if the triangle is coplanar to line and line is collinear to an edge of the triangle.

# Remarks

Use Intersect3d(Line) for non-coplanar intersection.
