SpaceCAD

SpaceCAD tells you if your model rocket is stable, how high it will go and which engine you should use. SpaceCAD automatically determines the stability of your model rocket. You can see your model rocket in 2D and 3D rendering. By just clicking a button, SpaceCAD calculates how high your model rocket will fly. SpaceCAD also helps you build your rocket design by providing multiple printout options.
