Recently two of my hobbies converged into an interesting modeling exercise. My interest in chess and the challenge I find in modeling objects I come across with SolidWorks were combined to recreate a fascinating rook design.
Modeling chess pieces is something in particular I find interesting, let’s take a look at how this one could be made. When I begin creating an object, especially one without known dimensions or drawings, I like to really get a sense of the big picture process ahead of time. In this case, the feature that I saw to be central to the part was the spiral staircase within it. From there, I would extrude the outer wall and then revolve the base, and pattern the ring of bosses at the top.
But then I was posed with the puzzle, how to model a spiral staircase. Up to this point, I was not particularly familiar with the Wrap feature, and so I toyed with 3-D sketching for a few minutes before deciding there had to be a better way. Sure enough, the perfect tool for the job turned out to be this particular feature.
As we can see here, to use the Wrap feature, we create a sketch on a plane tangent to a cylindrical face. Then this face will be “wrapped” around it and extruded out a certain distance. In this case, I was able to create my stair in just this quick and easy step (pun intended).
The rest of the process followed quickly, and now here is my rook!
As you can see, the next step I could continue with would be to cut the brick pattern into my outer wall. I could use an appearance of brick within SolidWorks, but if we wanted to model it, what would you do?
