We have a set of contour curves which we want to loft to create a surface.

Additionally we defined some guide curves which connects the contour curves.

For lofting the curves we use the following function:

var surf = (ISurface)Modeler.CreateLoftSurface

    (CurveArray: contourCurves

    , BBlendClosed: false

    , BForceCubic: true

    , GuideCrvArray: guideCurves

    , StartMatchingType: 0

    , EndMatchingType: 0

    , NormalAtStartSection: Vector3.UnitZ.ToSWVector(MathUtility)

    , NormalAtEndSection: Vector3.UnitZ.ToSWVector(MathUtility)

    , StartMatchingFaceList: new IFace2[0]

    , EndMatchingFaceList: new IFace2[0]

    , DegeneratedStart: false

    , DegeneratedEnd: false

    , StartPointOfStartSection: startPointOfStartSection

    , StartPointOfEndSection: startPointOfEndSection

    , SectionIndexStart: 0

    , SectionIndexEnd: sectionIndexEnd

    , GuideIndexStart: 0

    , GuideIndexEnd: guideIndexEnd);

This creates a surface, however it seems to ignore the guide curves (it doesnt follow the guide curves).

Can anybody give me an explanation of how to use CreateLoftSurface respectively the parameters for CreateLoftSurface?
