IHitTest3D.HitTest3D Method

Locates a part of a geometry closest to a query point. Any located part must be within searchRadius units from the query point.

[Visual Basic .NET]
Public Function HitTest3D ( _
    ByVal QueryPoint As IPoint, _
    ByVal searchRadius As Double, _
    ByVal geometryPart As esriGeometryHitPartType, _
    ByVal hitPoint As IPoint, _
    ByRef hitDistance As Double, _
    ByRef hitPartIndex As Integer, _
    ByRef hitSegmentIndex As Integer _
) As Boolean

[C#]
public bool HitTest3D (
    IPoint QueryPoint,
    double searchRadius,
    esriGeometryHitPartType geometryPart,
    IPoint hitPoint,
    ref double hitDistance,
    ref int hitPartIndex,
    ref int hitSegmentIndex
);

[C++]
