IConstructCircularArc.QueryFilletRadiusRange Method

Returns minimum and maximum radius for fillet to touch both input segments. hintPoint can be nil or can be a location near the desired fillet.

[Visual Basic .NET]
Public Sub QueryFilletRadiusRange ( _
    ByVal s1 As ISegment, _
    ByVal s2 As ISegment, _
    ByVal hintPoint As IPoint, _
    ByRef minRadius As Double, _
    ByRef maxRadius As Double _
)

[C#]
public void QueryFilletRadiusRange (
    ISegment s1,
    ISegment s2,
    IPoint hintPoint,
    ref double minRadius,
    ref double maxRadius
);

[C++]
HRESULT QueryFilletRadiusRange(
  ISegment* s1,
  ISegment* s2,

  double* minRadius,
  double* maxRadius
);

[C++]

Parameters

s1 is a parameter of type ISegment

s2 is a parameter of type ISegment

hintPoint

hintPoint is a parameter of type IPoint

minRadius [out] minRadius is a parameter of type double maxRadius [out] maxRadius is a parameter of type double

Description

A Fillet Arc is a CircularArc constructed between two input segments such that the CircularArc is tangential to both embedded segments at the Fillet Arc endpoints. QueryFilletRadiusRange determines the Maximum and Minimum Fillet Arc Radii in the region of the given Hint Point that can be used in ConstructFilletRadius such that the endpoints of the Fillet Arc lie on both input curves without extension. If no such Radii exist for the given Hint Point, an error is returned.
