I had a thought and wanted to get a consensus of the idea. Most free models are in two forms. Adobe PDF and Jpg format images. Why couldnâ€™t these models be Reverse Engineered? Iâ€™m not talking about changing something here or something there. Iâ€™m talking about printing out the original model and drawing it by hand to get an idea of what you are doing and then adding and improving to it. Even making a scale on the image to better facilitate a scale when built. Then making a digital image of it. The thought came to me in two phases. One, the model I had in thought was not the best idea and could have been approved on and added to greatly. Some of the things thought of to add or modify was things like. Head lights, Window imagery, Grills, and anything else that a capable person can think of and implement. The second is scale, The idea came across me by thinking about how fiddler Greens models are made on the image to represent a specific scale and made to be reduced and enlarged to fit a scale such as N, HO, and what not. Ok, I know this is a touchy subject, but lets say you did this. You redrew the who model and made significant upgrades and changes. If you were to print both the original and new models there were a few similarities. Now keep in mind that just about everything was changed about the model but the basic principle of the idea came from an original created by some one else. Releasing the model: So now comes the morality of it all. Do you keep it for your self and share only with your closest friends. or do you officially release it? Keep in mind what you have done to the model!. You may ask as I did to myself, how far did you change it? Well, How much change of a model would you consider enough to be released as a new design or new model? I know that this is a touchy subject, and borders on the â€œPiracyâ€ thought of things. I would really like to get an idea of the thoughts of others on this. If I didnâ€™t care about what other people thought of this than I wouldnâ€™t of cared to even write this post. Please post your thoughts and opinions.
