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 . You cannot create or modify an ArcSDE schema in AutoCAD Map 3D.
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.

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.
AutoCAD Map 3D uses facilities provided by ArcSDE for and . (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 metadata for ArcSDE schema—it uses existing metadata only.
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
