The first step to recreating anything is measuring it and representing those measurements digitally. This can be accomplished by manual measurement, 3D Scanning, or, in this case, 2D Scanning. When the geometry being measured is flat, or along one plane, a 2D scanner (or in my case a printer's copying machine) does a fantastic job mapping the geometry on a digital image file like a .TIF or .JPG.

I simply placed the gasket into the copier and scanned it at 600 DPI (Dots Per Inch) on both sides. Sometimes, depending on the color of the gasket, a piece of black paper as the background should be used. 

The scanned image can then be imported as a canvas in Autodesk Fusion and used as a template to recreate the geometry in a sketch. Proper scaling is important, so ensure the image is scaled to the real-life gasket. After scaling, one of the bolt hole centers was aligned with the origin, and I traced all the cut shapes (outline, ports, bolt holes). After tracing the "blank" cut geometry, the embosses were created and the coating was added as a 0.01mm surface over the part for reference only.
