Thanks for that tip. I don't own SCARM or RR TRACK software, but I applied your suggestion to ANYRAIL software. I got it to show a 1:1 size image on screen of the Lionel track curves I need for my project: O31, O42, and O54. I haven't yet figured out how to PRINT the image via my PC Printer. ANYRAIL has a built-in option to save an image as a JPG file -- which is what I need, but I haven't figured that out yet.
Since I'm working with Lionel tubular track, the suggestions of other hobbyists for other track manufacturers aren't applicable to my project.
