The time taken to achieve this, assuming you are proficient in 3D-cad-modelling and already have access to the relevant high-end cad packages and a suitable workstation (i.e. expensive), would not be insignificant; this six inch length of track has taken several years of my spare time to get this far: 100_010848_190000000.jpg A 1 in 6 left-hand common crossing using post-1924 castings based upon the LNER drawings of the time modelled in Scale7 on a Templot-drawn image.
