I’ve worked on a 3D model so I could visualize both the benchwork and the layout. This is particularly tricky for me while designing the “no-lix” grade track and figuring out how the benchwork would work in practice.
Constructing this model was both fun and educational. I’d advise anyone considering a larger layout to make a model. Its fun and helpful.
