AutoCAD Drawing Database (DWG) and AutoCAD Drawing Interchange Format (DXF)
AutoCAD Drawing Database (DWG) files are vector files used as a native format for AutoCAD drawings.
The Drawing Interchange Format (DXF) is a tagged data representation of the information contained in an AutoCAD drawing file. The Drawing Interchange format is a native file format of AutoCAD. It has become a standard for exchanging CAD drawings and is supported by many CAD applications. The Drawing Interchange format is vector-based and supports up to 256 colors.
| To import an AutoCAD Drawing Database file (DWG) or AutoCAD Drawing Interchange Format (DXF) |  |
| 1. | Click File |
Import. | 2. | Locate the folder in which the file is stored. |
| 3. | Do one of the following: |
| • | (Windows 7 and Windows 8) Choose DWG - AutoCAD (*.dwg) or DXF - AutoCAD (*.dxf) from the list box next to the File name box. |
| • | (Windows XP) Choose DWG - AutoCAD or DXF - AutoCAD from the Files of type list box. |
| 6. | From the 3D projection list box in the Import AutoCAD file dialog box, choose a plane projection of a three-dimensional object as seen from a given focal point. |
| 7. | In the Scaling area, enable one of the following options: |
| • | Automatic — scales the drawing using the scale of the AutoCAD source file |
| • | English (1 unit = 1 inch) — lets you scale the drawing in inches |
| • | Metric (1 unit = 1 mm) — lets you scale the drawing in millimeters |
| If you want to reduce the number of nodes on the imported object, enable the Auto-reduce nodes check box. |
| If the file is password protected, type the password in the Password box. |
If views are specified in your file, they appear automatically in the 3D projection list box.
If your computer is missing a font that is included in a file you are importing, a PANOSE font matching dialog box appears and lets you substitute the font with a similar font.
| To export an AutoCAD Drawing Database file (DWG) or an AutoCAD Drawing Interchange file (DXF) | |
| 1. | Click File |
| 2. | Locate the folder in which you want to save the file. |
| 3. | From the Save as type list box, choose one of the following options: |
| 4. | Type a filename in the File name list box. |
| 6. | In the Export to AutoCAD dialog box, choose an AutoCAD version from the Export version list box. |
| 7. | Choose a unit of measure from the Export units list box. |
| 8. | In the Export text as area, enable one of the following options: |
| • | Curves — lets you export text as curves |
| • | Text — lets you export text as editable characters |
| 9. | In the Export bitmap as area, enable one of the options to export the bitmaps in a drawing to a supported bitmap format. |
| 10. | In the Fill unmapped fills area, enable one of the following options: |
| • | Color — fills all unmapped fills with color. To change the color, click the Color picker and choose a color on the palette. |
| • | Unfilled — leaves unmapped fills unfilled |
| AutoCAD Data Interchange Format (DXF) technical notes | |
| • | The program supports AutoCAD files from version R2.5 to 2013. |
| • | Layers are retained on import and export. |
Importing an AutoCAD DXF file
| • | If a DXF file is too complex to import into Corel DESIGNER, you can configure your AutoCAD output device as an HP7475 plotter and perform a plot-to-file of the drawing. Then you should be able to import this plot file using the import filter. Newer versions of AutoCAD allow you to create EPS files. |
| • | Corel graphics programs try to center the imported image. The image is scaled down if the coordinates are larger than the maximum page size available in Corel DESIGNER — 150 × 150 feet. |
| • | Model space pages are imported as master pages. |
| • | Solid and trace entities are filled. |
| • | Dimension lines are imported as curves, not as dimension objects. |
| • | A point is imported as an ellipse of minimum size. |
| • | Files exported as "Entities only" may not appear as expected in the Corel program because of a lack of header information. |
| • | Imported AutoCAD files that contain formatted paragraph text preserve text formatting such as spacing, alignment, and indents. |
| • | Justification of text entries may not be preserved, especially if fonts are replaced in the imported files. For best results, avoid justification of text. |
| • | If the DXF file contains a font that is not on the user's computer, the PANOSE font matching dialog box lets the user replace the font with an available one. |
| • | Lines with a number of points that exceed the maximum supported in Corel DESIGNER will be broken into multiple lines, and their fills will be dropped. |
| • | 3D solids are not directly supported in Corel DESIGNER. Users can import 3D solids with the 3D Import program. |
Exporting an AutoCAD DXF file
| • | Corel DESIGNER saves drawings in a vector format accepted by computer-aided design/computer-aided manufacturing (CAD/CAM) programs and devices, such as AutoCAD and certain computer-driven sign and glass cutters. |
| • | Password protection is not available in the exported files. |
| • | Only the outlines of objects are exported. |
| • | Filled objects with no outlines have an outline appended to them on export. |
| • | All text is exported by using a generic font. Text formatting is not preserved. |
| AutoCAD Drawing Database (DWG) technical notes | |
| • | Corel DESIGNER can import AutoCAD files from version R2.5 to 2013 and export AutoCAD files from version R2.5 to 2013. |
| • | If the DWG file contains a font that is not on your computer, the PANOSE font matching dialog box lets you replace the font with an available one. |
| • | Password protection is not available in the exported files. |
