... DPI (dots per inch) setting. I found that it worked fine at 100 DPI, but not at higher settings: 2_050720_070000000.png 100 DPI means everything is rounded to the nearest 10 thou. That's probably fine for the sketchboard items, but not good for the track templates. I usually recommend at least 300 DPI for those, and 600 DPI looks neater. Here is a close up from your plan at 100 DPI. You can see that the rounding effects at 100 DPI produce wonky rail lines and varying rail width: 2_050716_120000000.png That's probably acceptable in 7mm scale, but discrepancies of this magnitude would obviously be unacceptable in 2mm scale. So ideally you need to make some changes on the sketchboard so that your plan will output at 300 DPI without errors. I will write more about that when I have done some more testing. Attached below is your plan as a 2-page PDF at 100 DPI (3MB), zoom out to about 10% to see it properly. regards, Martin.
