Step 1: Drawing the Curved Top

There is a nice video here to demonstrate how to do the loft with a rail to make a heart shape. The beauty of Fusion 360 is the mirroring capability. Draw only one side and once you are happy with it, mirror it and patch the back and extrude the back by 3/8 inch.

Step 2: Drawing Your Text on the Curved Surface

The key to this is extruding from the surface as demonstrated in this video. With the current version of Fusion 360 I could not get the two mirrored sides of the lid to be one body for the purpose of engraving across the entire lid. I had to choose one side or the other. You could do two separate drawings if you wanted your lettering on both sides of the top of the lid. I engraved on the inside of the lid as well.

Step 3: Manufacturing

To get the lid to fit snugly but also leave room for varnish I found that I needed to remove .03 from the contour on the lid piece that fits into the bottom of the box.
