its rare I actually refer to my work as CAD, though I suppose it is. To me it’s just a model I create on the computer instead of plasticard etc, sometimes I’m simp,y drawing a prototype. What I’d like to do here is show you a step by step guide as to how I created Hadlow Road and Hassan Green boxes (both are the same wood structure, but Hadlow Road is its preserved location and guise for those up in the CLC area) After a site visit in Feb 2017 with a friend, all the main dimensions were taken of what survives in preservation at Hadlow Road. It had been moved here for preservation on the station site following the BR line closing at Hassal Green. It was later found to not be as original and was much butchered, so I can only reinforce that photo reference still plays a huge amount of info. So, a start was made on the upper structure. Here we see the main 4 verticals timbers Andy horizontal timbers. This is quite a simple start. It gives the window lines on 2 sides, but waits the door position and windows on the third side. We then add the floor. The back at this time was going to be all timber. More about that later. So We move on a bit, the slanted outside timbers are all in below and above the window line. Also visible are the vertical inside timbers. The third side and door frame are now also installed. Same again from another angle. Why does the triangle top half only extend to the window inside? It’s to do with the internal roof. All will become apparent in the next few pictures. So now we have the internal roof in place (this gives a nice void to hide light fittings and batteries) and can be slid out. The first of the window frames have also been drawn and put in situe. All the windows complete... or so I thought... more about that later. Note also the internal panels have been coloured. Another angle. And from the rear.
