How to transform a surface into a solid object?

[Anonymous]

I need to convert some surfaces into solid objects (in particular the lower part (the hook)), you can see attached my file done in Fusion 360 (version 2.0.10806). I've tried to transform them using the patch tool where there are surfaces that don't coincide. Then I've used the stitch function to select all the surfaces involved, but at the end the final object obtained is still a hollow object. I've tried also the boundary fill function, but with the same wrong result.

Can someone help me finding a better procedure to obtain a final solid for the lower part of my file (the hook)?

Are there any unresolved issues highlighted in yellow in your Timeline?

Does Ctrl b (CMD b) return any errors?

No Form features were needed to create this geometry.

I would expect to see Tangent constraint here.

Seems like I have seen this problem before - did it come from a textbook?

If yes, what is the title and author of the book?

You were on the right track up to Sketch23 when you started using Forms.

You need to get your Rails/Profiles corrected and then this Loft will work as it should.  (see Attached)

I will change the sketch, using the tangent constraint. I've found the drawings from a cad website, I attach it.

Give it an honest effort before you look at the Attached...

When we use the loft selecting the rails and the profiles, it gives us an error: it says that the rails don't touch the profiles in some points. Looking at your example, redoing the loft operation, we obtain the same error, so how did you succeed in this operation?

I made some changes to my previous quick attempt.

See Attached.

In the pic attached you can see  the problem that I've mentioned in the previous answer. This is obtained redoing the loft in your file example. Do you understand why?

Without seeing you redoing it or your new/updated design, we have not way of analyzing what might have happened.

Ha!  I though I remembered seeing this hook somewhere before.

Turn off Chain select and then select each individual arc in your Rails.

We still have some problems with our model, because at the end of the loft operation, the software gives errors related to the rails not intersecting the profiles. We have tried to modify these profiles, but it's not possible to change the situation even zooming a lot. You can see attached a screenshot of the problem and our file. Can you give us some hint on how to fix this problem?

Thank you

What are these white dots at ends of lines?

Why is right side line an object line rather than a construction line?

Are there any unresolved issues highlighted in your Timeline?

I recommend starting over (that is EXACTLY what I did (TWICE - see Post #4 and #6)).

If I felt the best path to follow for myself was to start over from scratch - how did you think you could take a shortcut on this path?

[TrippyLighting]

It would probably help if you fixed the yellow warnings in the timeline:

I would also recommend cleaning up your sketches. there's not good reason to design with overlapping lines in a sketch.

I've succeeded in solving the problem, thank you for your help
