In this chapter, we will look at SOLIDWORKS and its software interface, as well as its main components. In addition, we will cover how to navigate through the software interface so that you will be able to easily navigate your way around the software in the upcoming chapters. We will also talk about the document's measurement system in terms of the different standard units it uses globally, such as feet, inches, centimeters, and millimeters for measurements of length. Interacting and setting up an interface with the software and setting up our measurement system will be the first two actions we will perform in any new project. 

The following topics will be covered in this chapter:

• Starting a new part, assembly, or drawing file
• The main components of the SOLIDWORKS interface
• The document's measurement system
