Introduces new vertices into this polyline at specified distances from the beginning of the polyline.
[Visual Basic .NET] Public Function SplitAtDistances ( _ ByVal polyCurve As IPolycurve2, _ ByRef distances As Double[]&, _ ByVal asRatios As Boolean, _ ByVal createParts As Boolean _ ) As IEnumSplitPoint
[C#] public IEnumSplitPoint SplitAtDistances ( IPolycurve2 polyCurve, ref Double[]& distances, ref bool asRatios, ref bool createParts );
[C++]
HRESULT SplitAtDistances(
IPolycurve2* polyCurve,
SAFEARRAY(System.Double)* distances,
VARIANT_BOOL asRatios,
VARIANT_BOOL createParts
);
[C++] Parameters polyCurve [in]
polyCurve is a parameter of type IPolycurve2* distances [in]
distances is a parameter of type SAFEARRAY(double)* asRatios [in]
asRatios is a parameter of type bool createParts [in]
createParts is a parameter of type bool
