NX 10 Trying to flatten a part

[dabiz7]

See attached image
Application is NX 10 Mach 3
I have a solid body, 0.10 mm thick, with same width slits all around, chunk out of one end, kind of looks like a Bellville spring

I wanted to use a sheet metal tool or some function in NX that would flatten this shape out on a plane so I can save as a DXF.
Not having any luck with any of the commands in Sheet Metal, don't have the Advanced Sheet Metal license
Converted Solid Body to Sheet Metal Part, selected Flat Solid, it crunches a little then comes back with "Unable to create body" Gee thanks
Tried Unbend, seems to do something, but not sure if this is the right tool.
Suggestions???

Attached is an example where I used the Unwrap Curve function to get the 'flat-pattern'.

Here's Johns model thickened and flattened. I drew two lines to show that you can include these in the flat pattern feature. Note that there is a separate flat pattern view in the part also and that i have displayed the flat solid for illustration purposes only. ( RMB on the Flat pattern feature and select "Make flat solid internal")

If you want to use Sheet Metal Application, you should use the "Lofted Flange".
Sketch two not closed Circles (e.g. 30° open) in a distance.
Lofted Flange: one arc is the start section, the other the end section.
Conus Sheets are not real "Straight Brake" Sheet Metal parts (this is what the SB means).
You just have one bend in one step (no continuous inclined rolling).
For that you have the group "Bend Section" in the SB Lofted Flange.
Mark "Use Multi-Bend Segments" - e.g. 30
You will get markers on the Flat Pattern where to set single Bends.
But you don't have to multi-bend. If you multibend, the conus in 3D will not reform to flat sheets which are connected by bends.
Sorry, I cannot upload the NX File, but hope the screenshot helps
