I've designed my models the old old fashion way. I usually just cut out paper, or cardstock and fold/bend parts to get it to look like what I want it to look like. Sometimes I have to modify the piece by cutting out a section, sometimes I have to glue it back on. Then when I get it reasonably close, I make sure the pieces are outlined in black, and scan them into my computer. Then, using MS Paint, I clean up the lines and print the parts out. (At this point they are just black outlines on paper). Then I try to assemble the parts and note on a second printout what needs altering. This may take several tries and alot of cardstock before the model comes out right.:cry: Eventually I get it where I want, then using ms paint again I begin to color the pieces in to whatever I am working on.
I've already done the Boeing Bird of Prey on this site and another, and the Boeing X-32A, using these techniques. I actually used a plastic model of the X-32 (un-assembled) to create the model I put out. That went real quick because I had something to go on more tangible than pictures and views. I can say at the moment I am working on several others, including the Valdore from Star Trek Nemesis:thumb:, (a way to go on this yet:cry

. Also the Desert Fox from Crimson Skies HRTR. These are a couple of my designs I am in the middle of right now. Don't ask when they will be finished, I pick one up once in a while, then put it down and work on one of the others. Hopefully I can have one of my models done in the next 2 months. When they are finished I will post the pictures.
I'd like to try some software, but at the present I really can't afford any of them. Pepakura seems to be the cheapest, but still has me a bit baffled. I find the problem with Pepakura is when you try to unfold something with curves, it breaks it up into thousands of pieces. I try to open a cylinder for instance and get way too many pieces. I would love to take a class somewhere, perhaps online, (I prefer real human interactionthough), and learn to use something that makes nice models without costing over $100 dollars, and can be done by simpletons like me. I've tried several, but I always have problems with the views. What I mean is that when I draw something say top view, then switch or swing to a side view the lines are skewed and when I straighten it that way then switch again to top view or oblique then the lines are skewed another way. It got so frustrating, that I quit trying for now. The best program I used for making something 3D like on the computer was the old X-Plane creator program. I could start with a cylinder or cone and the lines stayed where I wanted them.
I really admire all you people who can turn these great models out so very quickly:thumb:, (less than a year-like mewall1).
