You can access spatial
and attribute data in an Autodesk Spatial Data
File (SDF). SDF supports spatial indexing and can store
geometric and non-geometric data with minimum overhead.
When you view and edit
features from an SDF data source, you can do the following:
- Select the feature classes to include
in your map.
- Set conditions to limit the features
in your map.
- Style, theme, and edit the features.
- Automatically update the data source
with any edits you make.
- View and edit the schema definition.
- Move SDF data into other geospatial formats,
to take advantage of better data sharing
procedures here apply to the current version of SDF (SDF3). For
SDF 2 files (created for MapGuide version 6.5 or earlier), you cannot
use these procedures. Instead, import
You can bring SDF data
into your map in three ways:
- Use Data Connect to
view and edit the data directly in the SDF file. Use this method
to edit geometry and attributes or to style and theme the data.

- Import the data into the current map,
which converts the SDF data to drawing objects. Use this method
to clean the data or to create a DWG file. You can export the objects
back to SDF.
- For SDF 2 files (created for MapGuide
version 6.5 or earlier), use the separate SDF
2 Import and SDF
2 Export commands.
