Never used CAD before, but I am pretty sure, like anything, it can be learned. My questions are thus: 1. What is a user friendly CAD brand? 2. How much does it cost? 3. Can it be used to plan out the above sketch using Bachmann EZ track components? (And yes, that is a double track main line utilizing two groupings of eight diamond crossings, not one line. Two parallell rail lines. These are the baseboards: They form a rough "C." I am aware that the side, all twelve feet of it, will need to come away from the wall for access. (Or maybe, once the scenery is in, maybe not. My experience with EZ track on this scale is that it works so extremely well that having immediate and easy access to every square foot is not so much of an issue). Thanks in advance for advice/commentary. I do know there are methods of baseboards that utilize more finesse, but simply put, that's not my bag. I like to run trains, not spend endless hours trouble shooting track laying issues.
