Correct. You'll note the layers are named for the material... Green is on the 2x4 layer, blue on the 3/4" layer and red is the 1/2" layer. If you check out the FIRST supplied drawings (see above post) then you'll get a full inventory of the parts. The FIRST drawings, however, don't give you the parts in a useful fashion for determining how much wood you need or how to slice it.
I recommend numbering each part as you cut it. Refer back to FIRST's drawings for details on the parts with holes or angle cuts. Note that the hole cut out of the top of the boiler is re-used to make the touch bracket at the top of the rope.
It took two of us about five hours in a well-equipped wood shop to slice up all the parts, and a couple hours for teams of students to assemble them.
Again, if you only want some of the elements, you can ungroup the various sheets and rearrange the pieces to get only those you want.
I also expect that you'll be able to recreate functionally identical elements using alternate methods...
