Loft gives me headaches

[NVNDO]

Hey everyone,

the "Loft" function is giving me huge headaches (since always) as I don't seem to understand how it works.

From my logic, and I'd assume, everybody elses too, one selects the two surfaces to connect and adds either on each  side or a center line, so the tool knows along which path to go. But 9 out of 10 times this does not work and I just don't understand the logic behind it. 

In this example I have a 100mm ring  at a distance of 30mm from a 120mm circle.

I placed a center-line from one ring to the other but it does not create anything. 

I tried clicking all alternatives as suggested in the Error-window, but nothing..

Hi

It's better to construct such structures using the surface method – first the external loft, then the internal loft.

Depending on the construction technology and aesthetic expectations, the entire structure can be constructed using the surface method to maintain a constant wall thickness.

Please attach your model for a better explanation.  Open your model, select the File menu, then Export and save to your hard drive.  Attach to a reply post.

You cannot loft hollow geometry. Create a solid loft between the two outer circles and then shell the result. That assumes the wall thickness will be consistent.

If that isn't the case, @kacper.suchomski's solution the best way to achieve hollow geometry.

Hi! If you are trying to create a Sheet Metal part, I suggest you use Lofted Flange command to create the solid body. Then use Rip command to create the opening.

Many thanks!

See two examples attached.

Edit the sketch dimensions to suit your needs.

The solution was much easier than expected. This approach worked flawlessly - Thank you so much everybody! 🙏🏼
