Mo, This is my first valley. Took me forever, but I learned a ton doing it. Mostly about components, and what you can and can't do in them. Also learned some hard lessons about layers, as some lines in some of my components ended up in different layers. Arrrhh. To delete the trash rafter "tails," I had to explode each of these rafters, delete the edges I didn't need, then resave them as new components. There might be a better way, but I don't know it. It took me about 5 hours to draw the first valley, and about 3 to clean it up. The second time (after I deleted the mess I'd made in the first valley which looked good but had lines going everywhere when you looked hard at it) it only took me about 3 hours to do everything. Still a long time, but faster. Here is the next version, with the braces you mentioned. The rest of the frame would also need some more bracing.
