Shell feature

[toddiferous]

Howdy.

I can't seem to get the shell feature to work with this model.  Do I need to join all components, or do they automatically join? How will the coil respond - should it be a half circle?  Is it best to shell first, then add coil after? 

Thanks for any help this model of a jar to work.

Is your Design Intent for 3/32 wall thickness for the entire part?

[toddiferous]

Thanks for the reply.

That is my goal - practicing by creating a model of a glass jar; the jar's upper lip is about 3/32" thick, so I'm using that as the glass thickness.  Of course, at the threads and the shoulder ring, there will be a raised exterior.  I ideally want the entire inside surface to be flush throughout, including the interior at the threads and ring.

I'd suggest shelling before putting the threads on then if you want the inside flush.

Cool.  Thanks for the tip.  Can anyone tell if that is what went wrong, or did I mess something else up?

There is another issue with one of your Fillets.

You might need to model this with thickness, or as surface shell and then Thicken.

I didn't dig deep enough to find the issue.

Hi Todd,

JD and Mike are right. This is feature ordering issue. You need to create the shell much earlier. The thread and the fillet does not need to be hollowed. Move the EOP to right below Fillet2. Create the shell with desirable thickness. Then move EOP all the way back to the bottom. You will see the artifacts of coils. Either change the coil profile or just use Delete Face -> Heal to remove those faces.

Many thanks!

Sweet.  Thanks JD, Mike and Johnson.

Johnson, I totally forgot about being able to move features - shuffled the End of Part, shelled, shuffled EOP back to the bottom, modified the sketches for the Coils, used Delete Face with Heal option toggled on, an ended up where I was trying to get to!
