About Data Sharing Methods

You can use several methods to share an AutoCAD Civil 3D drawing data with people who do not have AutoCAD Civil 3D.

The following table lists the features of each method:

Data Sharing Method

Use of objects in other AutoCAD-based applications

Status of objects in other applications

2D and 3D style display settings honored in different viewports

Objects still exist when reopened in AutoCAD Civil 3D

Proxy Graphics

View/plot objects and design data; no manipulation of objects.

Objects are displayed as proxy graphics with no intelligence.

No

Yes

Object Enabler

View, plot, copy, and manipulate object labels. Design data is not editable.

Objects are maintained as intelligent objects.

Yes Yes
Export Civil 3D Drawing (to DWG or DGN) Objects are exploded to AutoCAD primitives. The visual integrity of the model is preserved. AutoCAD Civil 3D object design data is not available. No objects in other applications. Only AutoCAD primitives. No No
Export to SDF

Points, parcels, alignments, pipes and structures are exported to the SDF file. Can be used in applications that can read SDF. AutoCAD Map can import this data.

Primarily a format for AutoCAD Map 3D.

SDF is a separate file. Original drawing is not affected.

Export to 3D DWF Uses the 3D display representations of the objects for display. Some objects do not have a 3D display component so are not displayed in 3D DWF. There is also object meta-data exported with 3D DWF. All of the objects export the meta-data. Autodesk Design Review or DWF Viewer is required. Autodesk Design Review or DWF Viewer is required. 3D DWF uses the 3D display component when exported. Original drawing is not affected.
