Detailed Design
This includes the creation of a complete set of assembly and detailed drawings or CAD design part files, for each part used in the design. Each detailed drawing must specify all dimensions and material specifications necessary to make the part. From these drawings a prototype must be constructed for physical testing.
Example
The following is an engineering drawing for the winning concept. An unexploded and exploded view of the concept are shown below, respectively.
An engineering drawing for each of the components of the final assembly is generally needed for this phase. However, for the purpose of this web page and space limitations, a drawing for the final assembly is the only one shown.
