Remember that without parts a drawing is a collection of elements. You could also say that a drawing without parts is in effect a drawing containing one part; the part and the drawing are one and the same. Each part has a name (more details are given later in this section), and the name of the part you are using is displayed in the System Status Line. In a drawing without parts you will see the name associated with the top part (default name Top) displayed in the System Status Line; all the elements of the drawing are in this single part.

In an assembly drawing certain parts will contain drawing elements, a name, and possible subparts. Other parts contain only a name and possible subparts, these parts are used as pointers to assemblies.
