AUTOCAD 2008 PREVIEW GUIDE
Drawing Management
AutoCAD 2008 offers new and enhanced functionality for managing the data within your drawings as well as for
managing externally referenced drawing data.
Working with DGN files
AutoCAD 2008 enables you to attach Bentley’s MicroStation
®
V8 DGN files to your AutoCAD drawings and
manage them as externally referenced underlays or import DGN data directly into an AutoCAD drawing. You
can also export DWG™ files to V8 DGN format.
You can use the new DGNATTACH command to attach a DGN file to your AutoCAD drawing as an externally
referenced underlay. When you attach a DGN file, it is displayed in the External Reference palette along with
other externally referenced files such as images, DWG xrefs, and DWF™ underlays. You can clip the display
area of a DGN underlay using the new DGNCLIP command and you can adjust its properties, including
contrast, fade, and monochrome, using the Properties palette or through the DGNADJUST command.

IMPORT and EXPORT commands.
After selecting a DGN file to import, AutoCAD displays the Import DGN Settings dialog box. Using this dialog
