Saving the Drawing
To save your work and remain in AutoCAD:
1. Click the Save button in the Quick Access toolbar.
2. If the drawing has not yet been named, the Save Drawing As dialog box appears.
3. Name the drawing in the File name text box, and then choose Save.
All saved drawings are called files. AutoCAD 2016 supports different file formats, including:
.dwg: AutoCAD 2016 drawing
.dws: AutoCAD 2016 Drawing Standard
.dwt: AutoCAD 2016 Template Drawing template file.
AutoCAD 2016 drawings can be saved in other formats as well as in pre-AutoCAD 2016 formats.
