Using Shell Feature

I have a base feature with 3 extrusions off it. I want to shell 2 of the features. It will shell the first feature as well as my base but wont shell the second feature. Any ideas?

Is something like this what you are after?

(once you have answered this question - I have some suggestions)

I couldnt open your file. Said cannot read RSe stream.

Oops, I am using 2012 while you are using 2011.

But now you are changing the problem?

Is this end what you were having trouble with?

Yep that is what I was trying to shell

In your part notice this

yep wasnt sure how to extend that to the flat surface. I actually want that pipe to sick up a bit but end with it enclosed where the flat surface starts

and.....

you are doing wayyyyyyyy too much work

and

your sketches aren't constrained.

I recommend you read this document

Ok i'll try that. Should all my circle extrusions be revolved or does it depend? Still new at Inventor only been using it for about a month on and off.

Thanks for the advise.

It would be fine to use Extruded Circles rather than Revolved Rectangles - I'll post my solution in a minute.

But what about this - this doesn't look right to me either?

I don't usually recommend one sketch - especially for a beginner, but I was able to create all of this geometry from a single sketch (I had to guess at some of your design intent).
