Figure 1   Football

Step1: Create a pentagon on XY plane whose excircle has a radius of 80mm.

Figure 2   Pentagon on XY plane

Step2: Create a hexagon. Draw a line from any corner of the pentagon in 3D Sketch, the angle between the line and the pentagon edge is 120 degrees. Then create a plane (Plane 1) based on this line and one edge of the pentagon. On Plane 1, create a hexagon which shares an edge with the pentagon.

Step3: Find the football center. Draw a line (shown as Axis 1 in Figure 4) along the Z axis. It is vertical to the pentagon naturally. And then draw another line (Axis 2 in Figure 4) from the hexagon center and make it vertical to the hexagon. Their intersection point is the football center.

Step4: With football center as a vertex, create pyramids based on the hexagon and the pentagon respectively.

Figure5   Create pyramids

Step5: Create a sphere shape centered at football center, set the diameter to 220mm. Then make a 2mm thick shell based on the sphere.

Step6: Pattern the yellow hexagon piece along the Z axis.

Figure 7   Pattern hexagon piece

Step7: Copy the red pentagon piece together with a yellow hexagon piece along Axis 2.

Figure 8   Copy one pentagon and one hexagon

Step8: Pattern the result derived from Step7 along the Z axis.

Figure 9   Pattern the result of Step7

Step9: Taking Plane 2 as a reference plane, mirror all shapes.

Figure 10   Mirror all shapes

Step 10：Move the mirrored half of the shapes 36 degrees along the Z axis.

Figure 11   Move the mirrored half

Step11: Render your design in KeyShot and get an attractive football for World Cup.
