AutoCAD Drawing Database (DWG) technical notes

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)

Back to Top
1 Click File Import.
2 Locate the folder in which the file is stored.
3 Choose DWG - AutoCAD (*.dwg) or DXF - AutoCAD (*.dxf) from the list box next to the File name box.
4 Click the filename.
5 Click Import.
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.
If you want to reduce the number of nodes on the imported object, enable the Auto-reduce nodes check box.
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
8 Click OK.
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.

1 Click File Export.
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:
• DWG - AutoCAD
• DXF - AutoCAD
4 Type a filename in the File name list box.
5 Click Export.
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

Back to Top
• The program supports AutoCAD files from version R2.5 to 2018.
• Layers are retained on import and export.

Importing an AutoCAD DXF file

• If a DXF file is too complex to import into CorelDRAW, you can configure your AutoCAD output device as an HP7475 plotter and perform a plot-to-file of the drawing. Then you can try importing this plot file with the HPGL 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 CorelDRAW — 150 by 150 feet.
• Solid and trace entities are filled.
• Dimension lines are imported 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.
• 3D objects are not supported.

Exporting an AutoCAD DXF file

• CorelDRAW 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.
• Files exported to AutoCAD version 2007 may not display correctly in AutoCAD 2007.
• 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.
