References

A reference attachment is a model attached to and displayed with the active model for plotting or construction purposes. A reference cannot be modified. You can attach, as a reference, a model that resides in either the open DGN file, some other DGN file, or a DWG file. This chapter covers:

User preferences that affect reference operations are set by choosing Preferences from the Workspace menu and selecting the Reference category.

To attach a raster image to the active model as a (read-only) reference, use the Raster Manager dialog box (File > Raster Manager). The next section pertains only to the attachment of models as references.

For information on DWG files and references, see References.
