Hi Adam, Lofting is not easy. You have to construct a new instance of MArgsRhinoLoft, which contains all the loft settings and curves. Then, you have to call RhUtil.RhinoSdkLoftSurface and pass it your arguments. There's no function in the SDK which is as easy as Rhino.AddLoftSrf in RhinoScript. I agree that there should be, but there isn't.
Let's assume you have a collection of 100 OnCurves, and you want to loft the first 10: 1) Create a new list of MRhinoLoftCurve and populate it using a loop Dim loft_curves As New List(Of MRhinoLoftCurve) For i As Integer = 0 To 9 Dim crv_section As New MRhinoLoftCurve() crv_section.m_curve = m_original_curves(i).DuplicateCurve() crv_section.m_bClosed = m_original_curves(i).IsClosed() crv_section.m_bIsPlanar = m_original_curves(i).IsPlanar() loft_curves.Add(crv_section) Next 2) Then, create new MArgsRhinoLoft and populate the values: Dim loft_args As New MArgsRhinoLoft() loft_args.m_loftcurves = loft_curves.ToArray() loft_args.SetClosed(<<value that indicates whether you want a closed loft of not>>) ....<<set other loft settings in similar fashion>> 3) Finally, call the RMA.Rhino.RhUtil.RhinoSdkLoftSurface() function with loft_args and an array of OnNurbsSurfaces. -- David Rutten Robert McNeel & Associates On Oct 20, 1:48 pm, "Adam Holloway" <[EMAIL PROTECTED]> wrote: > I'm relatively new to scripting.
