You can bring features from an Oracle data source into your map, creating a feature layer in Display Manager.
To bring in features from Oracle
Optionally, select Remember Password if you want AutoCAD Map 3D to log you in whenever you open this drawing.
To select from a list of data stores, click the down arrow.
If the data store is not in the list, it may not use a AutoCAD Map 3D schema. Select Show All Data Stores to add these to the list. AutoCAD Map 3D creates a mapping to use these data stores with AutoCAD Map 3D.
If this feature source contains only a single feature class, that feature class is selected automatically. If it contains multiple feature classes, you can do either of the following:
If a feature class contains multiple geometry types,and you select the feature class itself, all geometries are added. To add a subset of geometries, hold your cursor over the feature class name to see the Show Geometry button. Click Show Geometry to see each geometry as a separate choice. Select the ones you want. Each selected geometry is added to map as a separate Display Manager layer.
To bring in a subset of the data, click the down arrow and select Add To Map With Query, where the properties for all geometries appear. To filter data after you’ve added the data to your map, see Filtering a Feature Layer.
