How do you create a new part document in SolidWorks?

To create a new part document in SolidWorks, you use the approach of navigating through the file menu. Selecting 'File > New' brings up a dialog that allows you to choose the type of document you want to create. By choosing 'Part', you are indicating that you want to start a new part file where you can begin modeling a 3D component.

This method is essential as it sets the correct environment for part modeling, which includes the tools and features specifically designed for creating and manipulating individual parts. The other options either lead to the creation of an assembly, which is intended for combining multiple parts, or they are not valid commands in the context of creating new documents. For instance, 'File > Open' is for accessing existing files rather than starting new ones, and 'Edit > New Part' is not a recognized command in SolidWorks' workflow for creating new documents. Thus, the correct sequence of steps for initiating a new part is clearly indicated by selecting 'File > New > Part'.
