Sheet metal

[cokhitp]

Please see the picture i attacked first.

The problem is:

With this part, i've already finished when using "model create". (3D sketch - helical curve, -> sweep)

So, i want to got the "flat pattern" drawing, but i dont know how to build this part in "sheet metal".

Please help!

To me that looks like one pitch of a screw conveyor flight scroll.

Unless there's something new in IV2011 I'm pretty sure it won't unfold because of the distortion that takes place during the pressing operation when you make a 'real' one.
