Hi, I am a 18 year old paper modeler from the states who is studying to become a mechanical engineer. I don't purchase models online, or download models. I have always made my own models, I guess the old fashion way with ruler and pencil, drawling out each side. i am intrigued by the auto-cad application I recently learned about on this site though. I have made my own simple models since 1st grade, and the past two years I have become more and more serious. I have built many models, most of them until recently have been castles, but now I am working towards making other types of models. I recently finished drawling out a R2D2 model, and want to make a copy of it before I assemble it. I will try to upload some of my work soon. So anyone else make models with computer programs?
