Recognizing that not everyone will be around for every event that out group might participate in, we decided to assemble together a set of modules owned by the CZM collective and use these to support shows with the addition of the personal modules that members may bring. Our first set of modules will support configurations from one to eight personal modules.
Below is a plan view showing seven personal modules (with pink baseboards) along with the necessary club modules (with cyan baseboards) to complete the layout.
You can see that with the removal (or addition) of various club modules the number of personal modules can change anywhere from one up to a limit established essentially by the number of backside straight modules the club has in reserve. At some point we will likely add another outside/inside set of corners to allow "U" shapes configurations ... could even add more of those corner sets for wraparound "C" and even more complex configurations.
Below is a 3D view of the configuration above. BTW, I'm using SCARM to create these plans and the 3D view.
