This is an infomercial pure and simple but it is a worthwhile one. Woodland Scenics makes an amazing variety of scenery products for use with model railroads (and other applications). Using them is simple but not always intuitive. This program in a tutorial produced by the company to teach the use of the product at an NMRA event.
The program probably makes using the products seem a bit more simple than it really is but it does show the potential of the products and teach how to use many of them. That is the purpose for which I bought it and I am not disappointed. It is well done and make the long commercial worthwhile.
