The Save As dialog box allows you to save the current document in a named file. The new file can simply be another file in the same folder or you can change the drive and folder so the document is saved in a completely different place. If you want to save the document in a different format use Export on the File menu.

If you click on a XAR or WEB file, you will see a preview of it in the dialog box (if the file contains a preview).

If you are editing a drawing which is embedded in a document in another program, this menu item will read Save Copy As. Selecting it allows you to save a copy of the drawing to disk without affecting the way it is embedded in the document in the other program.
