Part of my vision includes having a 3D model building tool for 17th Century ships

What we really need is a software tool that reduces warship 3D model building to "drag and drop". You would also have a set of prebuilt components that could have properties set to define dimensions at some level. I would want options to build models suitable for gaming or to build models suitable for high-quality illustrations. Right now, the only options are to use something like 3D Studio Max, Rhinocerous, or a lower end tool like Anim8or, and do a lot of work and take a lot of time (at least depending on your experience level). So far, the learning curve is winning, as I have made only minimal progress (despite a burning desire, held back by limited time). I hope to be able to procure at least an educational license for the two commercial products. Anim8or had be had for free. It is still quite capable, in experienced hands.
