Flatten bent tubes in SolidWorks and find bend positions in drawing

Drawing a bent tube in SolidWorks is not difficult in 3D-Sketch environments, but making a bent tube for fabricators is a nightmare. It is not the same as sheet metal in which you can easily make a flat pattern in drawing. In this video, you learn how you can flatten a bent tube in SolidWorks and find bend positions to make a clear drawing of the part.
