Chess Bishop Tutorial

1. Go into the front view
2. View -> Image Plane -> Import Image and import a reference image
   
3. Use the CV curve tool to trace the right side of the bishop. Don't trace the side with the slit, as we'll do that later.
4. Select the curve you just made and use Surfaces -> Revolve
   
5. Delete the reference image and the curve.
6. Move into the perspective view and create a cube. 
7. Transform the cube so that it is inside the bishop where you want the slit to be, and is also the same width and depth of the slit. The cube should take up most of the diameter of the bishop
8. Deselect all objects
9. Go to Surfaces -> Booleans -> Difference
10. Click on the Bishop and press enter.
11. Click on the cube and press enter.
12. The tool will run and you'll have a bishop.
