when hovering over these 2 sections of Kato track in the track selection window, they both display as the same size, 2 1/2" when looking at the info displayed at the bottom of the screen. The appear to be the correct sizes when used in the layout, which would be 2 1/2" and 2 7/16". Just had me confused for a minute when looking for specific sizes.
Please open the SETTINGS tab, and under Units, set the precision to 1/16.
You probably have it at 1/4 or 1/8, causing the length to be rounded to the nearest fraction of 2 1/2.
That't it, thanks.
