Sheet Metal Cone

Is it possible to make a cone with sheet metal that can be unfolded?

Yes. Post what you have and the version used.

I have attached a AI 2009 part file of what I want flattened. I thought I would be able to use contour flange but wasn't able make it work. What I ended up doing was using extrude and then shelling it but when I pressed flat pattern it gave an error about the thickness. Somehow I have to use face to get the sheet metal properties. I just don't know how.
Any advice would be nice.

Press the "sheet metal defaults" button, (uncheck use thickness from rule if its checked) set thickness to .0478 and click okay.

Then select (highlight) the inside surface of your cone and press the flat pattern button..

I noticed that Sketch1 is placed at the origin but not constrained to the origin. If you would set Inventor up correctly it would have been automatically constrained.
Shell does not result in the correct sheet metal flat pattern. Although it will flatten if set the thickness correctly - go to wireframe mode and examine top and bottom of flat pattern. You will see edges are not cut perpendicular to flat.
Sketch2 is not needed - you could have used the YZ plane to Sculpt or Split the part.
In fact you could have simply sketched an angled line and revolved a surface 180°.
Then Thicken to get the correct part.

when you shelled the solid the top and bottom edges were not square to the sides. Inventor may have had a problem with this. A slanted line rotated around an axis as a surface and thickened might be tried . A tilted rectangle using three point rec and rotated around an axis may also work. Highlighting one surface before flatten command will sometimes help.

Here is the proper SM part. Note that I did not change or
repair your geometry. You need to follow JD's advice on fulluy dimensioning -
contraining - anchoring all geometry in you sketches - every time. This is just
good practice to avoid downstream editing issues.

 

Go through the steps in the browser with the eop to see how I
did it....

I understand this an old listing, but I did a revolution and rip which reported a problem - just wanted to point out that you can solve this by increasing distance from center and then you can rip...

I don't understand the problem or solution - can you attach the ipt file here?
