In this tutorial, you will use a modeling technique called overbuilding and trimming. With this technique, you will create simple swept surfaces to define the main shape of the design. You will then combine these surfaces using intersecting and trimming.

As the vacuum cleaner design is symmetrical, you will save time by only building and detailing one half of the model. When the design is complete, you will copy and mirror the surfaces to create the full model.

The workflow you will use to create the vacuum cleaner model is shown below.

First, you will create the main surfaces, and then intersect and trim them to create the body shape. Throughout the tutorial, you will build one half of the vacuum cleaner, and at the end, you will mirror the surfaces to create the completed model.

Then, you will fillet the surfaces and add design details, further trimming the main shape.
