Is there a way to get Solidworks to generate a relief cut pattern for bending angle?

For instance:

I have a piece of angle (L3x3x3/8) that should be rolled to a 44'-7 3/4" radius. The length of the angle is 15'-6 7/8" long. In order to save some money, my client wishes to make relief cuts in one of the faces of the angle and then form it to the radius that is needed.

Given the design, I am OK with doing this - but he would like for me to give him a detailed drawing showing him exactly where to make each cut.

He will be using his plasma cutter - which produces a 1/8" kerf per cut. Doing the math, each kerf will garnish a 2.73° angle (if pivoting at the inner face). The design calls for a 20° angle. So, 8 cuts will be required - all rough math.

Does Solidworks have a feature that will automatically do all of these calculations and show where each cut should be?

Kevin Andrews - I don't think so... SolidWorks Sheet Metal isn't designed to develop flat patterns with the inner radius of an angle, which makes it a nonuniform part, the Sheet Metal Features are designed for a uniform thickness part.

But it still is a good question, maybe Frank Ruepp would be able to explain it more in detail.
