I need curved pipe but the end dimensions are different so Sweep doesn’t work. The manual suggests using loft but that cannot be made to follow the curve (it connects in a straight line). I’ve looked on the forum but nothing I can find deals with this - it shouldn’t be a problem but it appears so! Solutions most welcome 🙂

You could actually use guided loft, but the curves will guide how the edges from one circle to another would change. Take a look:
After doing this, you could use the Shell tool to make it hollow.

You can use the sweep tool with one of diameter, after it tap one of the end, scale and use the shell…

If both ends are the same shape where one end is larger than the other then Sweep could work. Do the sweep then select the face to change and use Scale.

Works too of course 👍

If you still need to loft it instead of scale it can be sketched simply in 2d first.
Left to right, you can sketch it in 2d and just rotate the circles so you can do guided loft.

Thanks for the suggestions. The ‘guided loft’ look useful.

Thanks for all who suggested the sweep then scale one end. Excellent!
When you know how 🙂 Thanks again.
