A lot of it probably depends on what you're used to. I see some of the programs that are presented in some form of 3D and they just confuse me. Not that AnyRail doesn't work in three dimensions because it does allow you to adjust track elevation and smooth slopes between any two points. Tell you the percent of grade too. I tried pretty much every trial and/or free program that was out there and just settled on AnyRail as the best for my eyes and what I was used to. The very best feature for me, however, on a layout that's essentially a huge square, is the I could print out the track plan (all 250+ pages) with an alignment grid included on those prints, and actually glue it straight down to my layout. Every single bit of track I lay is ultra-precise and no having to essentially re-draw or re-measure the layout once it's been finished on the computer.
I think any program is going to take some figuring out, and AnyRail wasn't any exception. I spent a lot of hours just playing and trying and figuring out what would work, both in the program and the real world. I had a small "test" layout that I designed and built before tackling this monster.
My layout, for what it's worth. Trackwork is about 20% complete at this point.
