Creating Intermittent Contour Flanges Along Edges

Autodesk Fusion 360 treats sheet metal bodies as one, there are no individual features.  Because of this fact, you cannot mirror contour flanges in the model.  You can however mirror the contour flange sketches which will save you a lot of time.  The main purpose of this video is to demonstrate the most efficient way to create intermittent contour flanges along a sheet metal edge.  In the drawing below, you can see the eight intermittent contour flanges along the outside edge of the sheet metal part.  I will demonstrate the process on four of them.
