Complicated Shape - Help!
(OP)
I have two issues:
1) I cannot get the mesh-like shape to FLEX a complete 360 degrees (leaving a small gap as shown below).
2) Perhaps because of issue #1, I cannot get the second step to work. The mesh-like shape that has a revolve (shown in blue) that I am trying to form to. In other words, I want the mesh-like shape to take on the form of the revolve. I have used the FLEX feature with no luck (although was successful with a less drastic "flare" shape, so I think it might be possible. Anyhow, I'm stuck and need help...please!

Extrude a slit cylinder (this will become the mesh) using the Sheet Metal Base Flange/Tab. Place the axis on the origin.
Unfold
Cut the mesh shape
Fold
Add the Revolve

I'll go have a strong coffee and take another look.

RE: Complicated Shape - Help!
Anyone have any ideas on then getting the mesh like geometry into the shape of the revolve???

RE: Complicated Shape - Help!
1) I needed to go back and recreate the part using circular revolve. That allowed me to get the part to fully close at 360 degrees.
2) Once I did that, the flex feature allowed me to bend the part without errors popping up.
Only issue that remains (and is there because I am "faking" the bends using the flex feature) is that the part features distort and become flattened out. I wonder if there is a way to keep the original thickness of the part while using the flex feature.
Thanks for the help everyone.
RE: Complicated Shape - Help!
I believe that with a little work the method I proposed will make a shape of uniform thickness that is wrapped around a shape. Can you please post images showing where the problem areas are? Thank you.

1. create an axis of revolution
2. sketch your inner shape
3. revolve #2
4. offset #3 outwards to the desired stent thickness
5. draw the desired stent shape (this may be many steps to get the exact shape you need) in this example I just did 1 sketch
6. project #6 onto #3 using a split line
7. with the newly created edge from #6 create a ruled surface outwards thicker than the desired stent
8. extend the inside edge of #7 so that the next step creates solids that extend past #3 and #4
9. thicken #8
10. split #8 with #3 and #4 to get the desired thickness.
11. mirror
12. pattern
13. combine to 1 solid
I hope this helps.
