The document describes three prototypes of a cargo ship designed by a group of students. The first prototype was created in Tinkercad and included a container, antenna, propeller, and lifeboat. The second prototype was created in 123D Design and featured a smaller, more detailed model. The third prototype discussed using 123D Make software and producing the 3D data for manufacturing. The group collaborated during planning, analysis, design, and execution stages of the project. Challenges included using the new software and creating detailed designs.
