To save a drawing, simply click the Save button in the quick access bar or use the SAVE command. The Save Drawing As window will open up. Specify a location, give your file a name, and save it.

If you save your file on a cloud account, such as OneDrive or Dropbox, AutoCAD will save the drawing history as well.  This drawing history is a new feature that you will find in the AutoCAD 2021 version only.

When you open a drawing saved in OneDrive, Dropbox, or Box, the Version History palette will open up, which will show a list of all drawing revisions, as in the following screenshot:

To open any older revision of the drawing, hover your cursor over the drawing and you will see a drawing Compare icon, as in figure 1.26.

Click the drawing Compare icon and older revisions of the drawing will open up in a window, showing new and older drawings compared using a feature called drawing compare, which will be discussed later in this book.

Once you are done checking the compared drawing, click the green checkmark in the Version Compare bar, as shown here:

If your drawing was saved by many other members, then the drawing history will show the name of the person who saved the drawing and you can use the name filter to select the drawings saved by any project member. You can also filter the drawing versions with respect to their dates. To open any drawing version, double-click on it from the drawing history palette and that version will open up in the drawing area.

So, this was all about the basic setup of AutoCAD and opening and saving drawing files. Before we move on, let's summarize what we have learned in this chapter.
