How to Save AutoCAD File as DXF: Step-by-Step Guide

To save an AutoCAD file as a .dxf, open your drawing, click File > Save As, then choose DXF (*.dxf) from the file type dropdown. Finally, enter a file name and click Save to export your drawing as a DXF file.

Syntax

In AutoCAD, saving a file as DXF follows this pattern:

• File > Save As: Opens the save dialog.
• Save as type: Select DXF (*.dxf) to export the drawing.
• File name: Enter the desired name for your DXF file.
• Save: Click to complete the export.

This process converts your DWG drawing into a DXF format, which is widely used for sharing CAD data.

Example

This example shows how to save a drawing named FloorPlan.dwg as a DXF file:

• Open FloorPlan.dwg in AutoCAD.
• Click File > Save As.
• In the dialog, select DXF (*.dxf) from the file type dropdown.
• Type FloorPlan.dxf as the file name.
• Click Save.

The output is a new file FloorPlan.dxf saved in the chosen folder, ready for use in other CAD programs.

Output

File 'FloorPlan.dxf' saved successfully in the selected folder.

Common Pitfalls

Some common mistakes when saving as DXF include:

• Not selecting DXF (*.dxf) in the file type dropdown, which saves the file as DWG instead.
• Overwriting important files by using the same name without backup.
• Choosing an incompatible DXF version for the target software.
• Forgetting to check the save location, causing difficulty finding the file later.

Always verify the file type and location before saving.

Right:
File > Save As > Save as type: DXF (*.dxf) > Save

Quick Reference

Step	Action
1	Open your DWG file in AutoCAD
2	Click File > Save As
3	Select DXF (*.dxf) as file type
4	Enter desired file name with .dxf extension
5	Click Save to export the DXF file

Key Takeaways

Always select DXF (*.dxf) in the Save As dialog to export correctly.

Check the save location and file name to avoid overwriting files.

DXF files are useful for sharing drawings with other CAD programs.

Verify the DXF version compatibility if needed for specific software.

Use Save As, not Save, to create a new DXF file without altering the original DWG.
