I've used RR-Track version 4 in the past successfully. Now I'm that I'm in the market for a new basement --I mean "house" -- I wanted to start playing with potential layout designs for the typical spaces I'm encountering. To see if a room or space will work well for me, I can draw out a rough idea and figure out if I can run enough wide-radius curves, avoid duckunders, etc. and deal with the locations for doorways, stairs and obstructions. Fortunately, I may have almost a year to go looking, and an understanding wife -- we both agree that the house needs adequate space for her hobby in knitting and spinning raw fiber as well as a space for my train hobby (instead of a decade of tiny Carpet Central carved out of my office space...). This will very likely be where we retire, so we're taking time to find something not too big, but sufficient for us and our pursuits which carry a little more-than-average need for good spaces and storage.
Aside from the option to simulate running a consist to check siding lengths and some clearances, how much has changed in version 5? Any significant enhancements in the menus and interface; anything it can do now that's a significant upgrade? Thanks in advance for any thoughts/ideas!
