How to flatten a cylindrical tapered part in sheet metal mode

Hi, I can't seem to flatten the attach part in sheet metal mode. I am able to do this on a round part. This is an 12" outer diameter part and is 1/8" thick with an offset in 2 plane. I want to flatten this in to 4 segments (one segment in each quadrant). Does not matter which face to use as the center reference for the quadrant. Any help would be appreciated.

Thank you,

Curious as I am, I could not get Inventor to do this, I did do it in Mastercam, using unroll. cool result.

Thanks for trying Jonathan & Advance. I still cant get it to flatten. I took a section of the part and still cant seem to get the part to flatten. See attach

Thanks

I'm not able to open your ipt because i can use Inventor 2014 only, so the following is depending on the picture.

I assume that you modeled a circular tube and cut it sloped. To unfold this part you should slot the part to achieve the unfolding.
But be careful - the slopped edges are not really sheet metal contours in the blank because the created cutting faces are not perpendicular to the blank.

the problem is, that you extrude your schetch by angle, make straight extrude, with defined thickness on sketch and then cut ends and make tear, only then it will unfold, i attached correct file but it is in 2017 so u will not open it...

Hi,
Please refer to my model in the attached file
