Drawing on a computer is like anything else. You start simple and build on it. There are programs like Visio by Microsoft that's called "Drawing for Dummies". It very easy to learn. Coreldraw is much more sophisticated and therefore takes much more time to learn. I am still learning things on it. RRTrack, on the other hand, while it is technically a drawing program, lays track really well, but is a terrible graphics program. It is 3D capable, but limited. You can elevate something off the platform base and you can extrude an object to a thickness, but you can't then tip that object relative to the base.
For the ultimate 3D experience, download a free copy of SketchUp and start having fun. It's the most clever, powerful drawing program for free in the world. They have many free video tutorials to learn how to do most everything and it's fun.
I did some checking and to have the poster-sized graphics printed by Kinkos would cost upwards of a hundred bucks, so Plan B is now in effect. I printed the whole thing tiled over multiple pieces of paper which I will carefully cut and put together and then adhere the whole thing to the back of the acrylic. If I do this carefully, the seams should be unobtrusive (not invisible, just not to noticeable). All of the electrical hardware fastened through the panel will keep most of the sheets from delaminating. Tomorrow I'll give it a try. This way it cost the price of the ink in my printer.
