For this assignment, we were tasked with creating an extrusion of a flat image and only printing in one color. To get the level of detail in the flat image, we used extrusion to differentiate the back ground from all of the details. I chose the symbols representing the four elements from Avatar: The Last Airbender.
Step 1: Insert the canvas image onto a plane in Fusion 360.
Step 2: Using a 2 point rectangle, sketch the perimeter of the entire shape. Then sketch the four individual squares of each elemental symbol. Using the fillet tool, round each of the edges of the inner four squares so that the fillet radius is 0.5 mm.
Step 3: Next, trace the outlines of each elemental symbol. I started with the earth symbol because it was the only symbol that I didn’t sketch only using splines. Start by sketching 3 2-point rectangles that all intersect. Then trim the sides that are mutual between the rectangles and fillet every corner so that the fillet radius is 0.5 mm. Repeat the process on the other side.
Step 4: Using splines, outline each of the elemental symbols. When the symbol comes to a sharp point, such as the ends of all the spirals or the flame in the fire symbol, end the spline and start a new one on the same point so the final product will be pointed and not curved. This process is long and tedious, so I only included a picture of the finished product.
Step 5: Select the outlines of each symbol by holding down shift and clicking each individual symbol’s components. The water symbol is only the blue outline, the fire symbol and earth symbols each have 2 components, and the air symbol has 3. Also select the border separating all of the symbols and extrude all of these sketches 5.0 mm. Everything else that was not selected, the white negative space in the symbols, select and extrude 1.0 mm.
