Creating Sheet Metal Flat Pattern of Round Object in Autodesk Fusion 360

Update (9/19): The method shown below is not required to create a flat pattern of a cylindrical component in the latest version of Fusion 360.  Selecting on the inside or outside face of the cylinder, as the stationary face, is now all that is required.  If you desire to use the Unfold tool, the method outlined in the blog and video still must be used.
----------------------------------------------------------------------------------------------------------- Autodesk recently released an update to their Fusion 360 application.  This update contained many wonderful enhancements and new features, one of these was the long awaited sheet metal environment.  The sheet metal environment is very versatile and can make most sheet metal forms and the flat patterns needed to fabricate them. 

There is one exception to creating a flat pattern and that is for cylindrical objects such as the sheet metal part below.  If you are wondering how to make the part with only the "Flange" command, apply it to an arc creating what you call a contour flange in Inventor.

Fusion 360 "Create Flat Pattern" command requires a flat surface along the surface to be unfolded.  Since this cylinder does not have one, you cannot execute the command on it.  The solution is to add a very small flat to the edge of the cylindrical surface.  I have created short video to illustrate this process.  Click the LINK to view.

By the way, this same technique can be the used with the "Unfold" tool as well.  Enjoy.
