1. A designer is given three features to create 3 solid models. In the first model, use Protrusion. In the second model, use Cut. In the third model, use both Protrusion and Cut. Note that you need to define the dimensions, such as D, H, A, B, and C when creating the 3 solid models. Therefore, you need to present all the dimensions, position and size, on your solid drawings. Present 3 processes, or sequences, to manufacture the 3 solid models.
