    How to find the intersection point of a curve with a trimmed surface.

    Johannes Kronberger

      We are starting with a body, a cylinder and then do

       

      var faces = body.GetFaces();

       

      for each face we get the surface using

       

      var surface = (ISurface) face.GetSurface();

       

      We then test if our curve intersects the surface via

       

      object _points = null;

      object _tArray = null;

      object _uvArray = null;

      double [] bounds = ..... // Calculate the bounds of curve

      var r = surface.IntersectCurve2(curve, bounds, ref _points, ref _tArray, ref _uvArray);

       

       

      However we find that IntersectCurve2 returns intersections on the infinite surface rather than the trimmed surface. What are we doing wrong?
