It first starts with an idea...
A project starts first as an idea. It is drawn onto paper to begin. Design requirements and other drivers are identified and are used to shape the design in both form and function.
The design is fleshed out into a 3D CAD environment. The flight surfaces are lofted with either off the shelf NACA airfoils or specially designed custom airfoil sections. The fuselage is lofted along with the empennage flight surfaces.
Once the aircraft is lofted, parts are identified and modeled. The 3D assembly is populated with all the parts and pieces that will be required .
