Hi guys,
I've been looking to develop a teapot spout using two sketches to sketches for the sweep/loft and another two sketches to act as the paths (Pic1).
Beyond adding a stack of sketches to guide a loft (Pic2), is there a way I can sweep the shape just using the four sketches in Pic1, perhaps using the Curves Workbench?
Huge thanks in advance.

Re: Sweeping using multiple edges
Thanks for the feedback guys.
I ended up sweeping to rail as it seems a less wieldy process (Pic3), but I could only get it to sweep the profile (on 2 rails) for half of the spout (I guess this is because the ruled surface runs through the middle).
I also got some strange artefacts when using the 3D offset in the Part Workbench to add thickness (Pic4).
Ended up mirroring the Approximation_Curve (without any offset) to complete the shape, closing the faces and converting the whole thing to a solid. Not the most elegant solution perhaps, but a result

Re: Sweeping using multiple edges
If I remember right, the Curves workbench dev recommends the Gordon surface tool over the sweep on 2 rails method.

Re: Sweeping using multiple edges
Thanks for the pointer. The Gordon tool looks to be really powerful. The only issue is that I can't seem to get the shape to 'close' (Pic5), so perhaps it's better suited to open shapes?

Re: Sweeping using multiple edges
I would do it in half (with a Gordon).
Then Mirror in Part workbench
Then us the Curves Blend surface to close the gap between the halves.
Check out those subjects in this playlist (probably #32 & #33):

Re: Sweeping using multiple edges
That did the trick nicely!
The only thing to add is that it seems I can't create a 3D Offset (in the Part Workbench) using the Gordon tool. Creating a solid works fine though
