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?
