Slice sheet metal?

[wolterh6]

I was designing a part which consisted in a circular sheet metal part with a hole in the center, and a bent rectangular radii-oriented section. The second feature is the one I want to give focus in this thread.

Take a circular sheet metal with a diameter of 30 mm and a thickness of 1 mm. Now, to achieve the bent section one would perform - in a workshop or any other equivalent - two parallel slices of about 5 mm in length with a distance from each other of 4 mm. The slice would start in the circumference and end somewhere nearer to the center of the disc, but not parallel to a radius (since its parallel to another slice 4 mm apart as said before). After the slicing was done, one would bend the section bewteen the slices 90 degrees to any of the sides.

Now, in Inventor I couldn't find a way to do this. I couldn't just slice a line through the disc. I worked it around by cuting rectangles of 0.2 mm in width and with the length of the desired slices, and then using the folding command to bend it 90 degrees. Is it possible to perform this so called slices?

I am using Inventor 2012 (Educational version). I already committed the modifications on the original ipt but I will attach it so you can see what I did.
