file. Each layer in the drawing file becomes a feature class in the SDF file. when you export it. Use the Export dialog box to map each layer to a target feature class. You can also convert object data to geospatial attribute data. Once you set up the mapping, you can save your settings as a profile, allowing you to use the settings over and over again. Using the Resulting SDF File Once the data is stored in the SDF file, you can connect to that SDF data store. Add the SDF features to a map as Display Manager layers. One advantage of geospatial data stores is the ease with which you can control attribute data (called "properties" for feature classes). In this tutorial, you add a constrained (page 309) property to a feature class in the SDF schema. A constrained property can have only one of a set of predefined values, or only values within a particular range. For example, you can define a Zoning property whose values can be only Residential, Commercial, or Public. Moving SDF Data to a Different Geospatial Format Once data is in a geospatial format, you can use Bulk Copy to move it to a different geospatial format. For example, you can copy SDF data to a set of SHP files. Converting the Data to DWG Format If needed, you can reimport your changes in DWG format. If you create a template file specifying the original layers for the data, you can place each feature class into its appropriate drawing layer. The data then uses the styling information for the drawing layer, rather than the styling you applied to the Display Manager layer. About the Managing Data Tutorial | 249
