Absolutely not. All of my routes objects and trains are coded using windows notepad. I was never able to work out how to use routebuilder. I downloaded it and read the instructions and tried to use it on several occasions without getting anywhere. I just could not figure it. After about two weeks I dumped it and got hold of Dennis Lance's tutorial and learned to write code. And I am glad I did it that way, because it gives me more freedom of expression. Routebuilder made work is fine, don't get me wrong, but I can tell when a route is made with that program, I suppose tthe program stamps its personality on the work. I would rather stamp my own personality on my work, as I think I have done.
So, my only tools are pencil and paper, windows notepad, Objectviewer, Routeviewer and Photoshop.
