Help w/AnyRail Carrera Track design.

Hey gents,

I just picked up a new Carrera slot car set and using Anyrail, ver.7.1 to create my layout. Since I already own it, and it's fairly popular, I've been creating or copying layouts from various sites. One thing I'm noticing, is most tracks are not connecting. Its either a half inch short or to long. Is this something you still should try and build or no?
