N-gauge Japanese-style Model Train
I am experimenting with photo-etching to make highly-detailed parts such as catenary poles or steel platforms. The parts are first modelled in 3D in Autodesk Fusion 360 using the Sheet Metal module. Fusion 360 is a powerful CAD/CAM/PCB professional tool available free of charge for personal use (check https://www.autodesk.com/products/fusion-360/personal).
These are a few examples of objects designed using this software.
