Build surface with curves

Can you help me build a surface for these curves…

Hello,
Is there a way to tween two curves across 4 guide curves?? I need to create a loft surface from these curves…

Hi @RANE
Well, you could either use Sweep2 with the closed end curves as the rails and the open curves as the sweep shapes - or you could give NetworkSrf a go. The latter is sometimes frowned upon by the Class-A purists here, since it will often give you some fairly complex surfaces, but in this case it might just fit the bill. If you insist on using Loft, you can extract the “center” isocurve from either of those operations and use that as the middle loft curve. Post 3DM file if you need more help.
