To create a DXF (Drawing eXchange Format) file, you'll need a graphic or illustration software package that creates the DXF AutoCAD file format. A DXF file is an ASCII (American Standard Code for Information Interchange) file with the two- and three-dimensional information representing a CAD/CAM (Computer Aided Design/Computer Aided Manufacturing) drawing. Purchasing AutoCAD to create DXF files is expensive; it's more cost-effective to create this file format with your existing graphics or illustration software, if possible.
Create a DXF File with Microsoft Visio
Launch Microsoft Visio 2003.
Click "File," then "Open." A dialog box is displayed.
Browse to your Visio drawing, select it, and then click "Open." The Visio drawing you selected is displayed in the center window.
Click "File," then "Save As." The "Save As" dialog box is displayed.
Click the drop-down arrow for "Save as type:," select "AutoCAD Interchange" and click "Save." The Visio drawing is saved as an AutoCAD DXF file.
Create a DXF File with Adobe Illustrator
Launch Adobe Illustrator CS.
Click "Open." The Illustrator "Open" dialog box is displayed.
Click the illustration to be converted to a DXF file, then click "Open" to display the illustration in the window.
Click "File," then "Export." The "Export" dialog box is displayed.
Click the drop-down menu for "Save as type:," choose "AutoCAD Interchange File (*.DXF)" and then click "Save" to create the DXF file.
