WFS Tab Interface
Understand the WFS palette controls used to add services, fetch data, and manage imported WFS entities.
Interface Overview
The WFS section of the Web Maps tab manages WFS service definitions and the feature datasets selected from those services. After a service is added, the WFS palette workflow can fetch feature data and manage the imported CAD entities.

WFS Palette Workflow
The palette begins with the service list. Each service contains selected feature types. Palette actions then fetch vector data, zoom to extents, select imported objects, or remove imported WFS objects.

Common Palette Actions
| Action | Purpose |
|---|---|
| Add WFS Service | Open the WFS Server Connection window and create a new WFS service entry. |
| Modify WFS Service | Reopen the connection window for an existing service and update its URL, credentials, selected feature types, or options. |
| Fetch WFS Data | Download the selected WFS feature dataset and create CAD objects. |
| Zoom to Data Extents | Use the WFS layer bounding information to zoom the CAD view to the server dataset extents. |
| Select Imported Features | Select CAD objects that were created from the WFS layer. |
| Zoom to Imported Features | Zoom the CAD view to the objects already imported from the WFS layer. |
| Remove Imported Features | Delete the CAD objects created from the selected WFS layer. |
| Remove Service | Remove the WFS service entry from the palette. |
WFS Result Tracking
SPCAD stores metadata on imported WFS entities and tracks the created object handles. This allows later palette actions to find the same imported objects for selection, zooming, refreshing, or removal.
Tracking is object-based.
If imported entities are manually erased or modified outside the WFS tools, some management actions may affect only the objects that still exist in the drawing.
