The software design strategy used in designing TJZOIDE strives to balance a rich feature set with ease of use, while making it affordable to RC modelers like myself to be able to design, build and fly models in turn around times of days rather than weeks. The material of choice is extruded foam. It is lightweight, strong, available in most hardware stores and easy to cut using a hotwire.
The software design makes building an airplane model as simple as possible. Wings are made by specifying basic measurements such as wingspan, chords, sweep back or forward distances and wing location in the fuselage. Fuselages are made by drawing cross sections and specifying how far from the nose they are located. That is it. That is all it takes to design an airplane. Of course, you can get as involved as you want and as exacting as desired. Many features have been added during the course of developing the software to support the model design and build process.
