... as a change from the battle of wits with the sketchboard. The idea is to curve a scanned prototype map track plan so that it can be fitted into a smaller space and used as a background guide for track planning in Templot. It worked out quite well and could be very useful. Here is the control template on an S-curve transition representing the desired running line for the model in the available space, and a scanned track plan imported into a picture shape which clearly won't fit that space as it stands: 2_191552_340000003.png The actual position of the picture shape is immaterial, because we are going to curve it and align it over the control template. On older systems there's time to make a quick cup of tea while Templot does its stuff, and here's the result: 2_191552_300000001.png You can see that I set the curving offset to match the up running line, and the scaling and curving has matched very well: 2_191552_260000000.png Of course, it won't be possible to copy the curved track plan exactly. A prototypical curved goods shed is going to ...
