Sweeping using multiple edges

[thehounsell]

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.

Hi and welcome to the forum!

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

If I remember right, the Curves workbench dev recommends the Gordon surface tool over the sweep on 2 rails method.

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?

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):

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
