Working with ESRI ArcSDE Data

Bottom of the Page

You can connect through ArcSDE to an underlying Oracle or SQL Server database. You can insert, select, update, and delete feature data in existing ArcSDE schemas . You cannot create or modify an ArcSDE schema in AutoCAD Map 3D.

AutoCAD Map 3D supports ArcSDE 9.3, 9.3.1, and 10.

Versions 9.3.1 and higher are available as either a 32-bit or 64-bit provider on Windows. (For previous versions, and on Linux, it is available in 32-bit only.) The 64-bit support is available only with the 64-bit ESRI ArcSDE client libraries versions 9.3.1 and higher. (The 64-bit client libraries were not available before version 9.3.1.)

Both 32-bit and 64-bit ArcSDE servers are supported for the 9.3.1 and higher versions. You can access either server type with a 32-bit or 64-bit client. For example, if you are using AutoCAD Map 3D in a 32-bit environment, you can access a 64-bit ArcSDE server.

To work with ArcSDE, you must install ArcSDE 9.3.1 or higherand a supported data source , such as Oracle 11g, in the network.

Install the following DLL files on the computer on which you run AutoCAD Map 3D:

For version 9.1 For version 9.2 and higher
pe91.dll pe.dll
sde91.dll sde.dll
sg91.dll sg.dll

For instructions on installing the DLL files and setting up your hosts and services files for ArcSDE, see Bringing In Features from ArcSDE.

The PATH environment variable must reference the local folder containing these DLLs. To accomplish this, you can install an ArcGIS 9.1 Desktop application or the ArcSDE SDK. For more information about ArcGIS 9.1 Desktop applications and the ArcSDE SDK, refer to the ESRI documentation.


This functionality affects geospatial feature data only. For information about linking records in an external database to objects in a drawing, see Overview of Linking Database Records to Objects. For information about moving data between DWG and ArcSDE format, see Migrating DWG Data to GIS.

What ESRI ArcSDE Schemas Support

AutoCAD Map 3D uses facilities provided by ArcSDE for long transaction versioning and persistent locking . (ArcSDE supports one or the other, but not both, on the same class). AutoCAD Map 3D uses the standard ArcSDE API and ArcSDE-supported storage on both the Oracle and SQL Server platforms. AutoCAD Map 3D does not use FDO metadata for ArcSDE schema—it uses existing metadata only.

Restrictions of ArcSDE Schemas

If ArcSDE encounters curved segments, it converts them to a series of line segments that approximate the original arc segment (an approximation of the original geometry). To specify how the arcs are segmented, see Setting Arc Segmentation Values.
