Ah, ok. Canon Locus has 52 layers. Each layer is like a bullseye with a ring every 200 meters, on the inside and outside of each ring are "lots" of what amounts to a spherical space up to 50 meters in diameter. So each band is about 110 meters wide. From the shell in the center radiate about 400 spars, where these transcect the layers and allow people to move between them. At the 45° points on the sphere the radial spars are larger (book doesn't say how large- my guess is 20 meters in diameter) and contain a tramway like system to move people longer distances more quickly. Besides the size comparison I had made a small rough model of the core using a Styrofoam ball and pins. I never did a version with the layers because the shift in scales between the full size of the hab and many of its component parts was a bit extreme. Perhaps someone with a 3D modeling program, 3D printer , or even some skills at Minecraft will build it.

Yeah that's where you start to run into some issues with the description. I went with what I call the "crowded Locus" model- rings every 200 meters regardless of where the spars intersect. This means there are free floating rings with no connection to anything else. Not an ideal setup but better than a habitat with a negligible quantity of rings per layer. I assume that there are cross spars that connect free rings and/or rings in the cone that run perpendicular to the layer rings and connect the layers where they end for the cone. On the 1:100 scale drawing in the section that has all the dots - those are the rings. The number at the end of each layer is the quantity of rings in that layer.
