... size of the full 3000 x 1000 image: 1. 16ft= 4876.8mm 2. So the image scale is 4876.8/ 2702= 1.8049 model mm per dot. And then: 3. The width of the image is 3000 dots x 1.8049 mm/dot= 5414.7mm. 4. The height of the image is 1000 dots x 1.8049 mm/dot= 1804.9mm. These figures can now be used to set the size of the picture shape. Click the modify shape tab and then the change dimensions... button: 2_172324_530000000.png and enter the calculated dimensions: 2_172324_540000001.png The picture shape will then be scaled to the model size, ready for the track plan to be designed over it, and you might want to shift it slightly to check that the Templot grid (set to feet) matches your drawn scale marks: 2_172324_540000002.jpg The cropped image file is attached below, and then I will post the BGS file so you can use it without going through the above stuff yourself if you prefer. cheers, Martin.
