So far with my chess set, I've completed every piece except for the knight, which is by far the most difficult piece. For the pawn and the queen, I simply did the bezier and revolve. For the rook and the bishop, I started with the bezier and revolve tool, and and then created a series of cube polygons and used "difference" under Boolean to create the negative space in the crown of the rook and the face of the bishop.
For the King, I once again used the revolve tool to create the main structure. To add the cross on top, I created a cube and added divisions to it. I then put it in face mode, and selected the two middle segments opposite each other and used the extrude tool. I then made it smaller and positioned it in place and then used Mesh --> Combine to fuse them together.
For the knight, I've been trying the same method that we used with the human, where we started with a revolved object. So far, it hasn't been too successful, and I'm thinking about using a cube instead.
For organizing my project, I've been using multiple layers for each type of piece. One for the bezier and revolved shape, and one for the polygon/NERB. This is effective for only viewing the pieces that I want to view.
