Line to Region
Notes:
Line to Region
Feature Description
Convert the selected line object to a region object, and save to a region dataset or CAD dataset.
When converting line objects to region objects: Closed line objects will be directly converted to region boundaries; Unclosed line objects will first be connected end-to-end before conversion. As shown below, Figure 1 demonstrates converting closed line objects to region objects, while Figure 2 shows converting unclosed line objects to region objects.

Feature Entry
- Features Tab->Feature Editing Group Dropdown->Line to Region.
Steps
- Open the line dataset in the map. With the current line layer selectable, select one or multiple line objects.
- In the Features tab's Feature Editing group Gallery control, click the Line to Region button in the type conversion group to open the Line to Region dialog.
- In the dialog: Select target datasource and dataset for storing new region objects. Two saving modes are available: save to existing dataset or create new region dataset. Parameters include:
- Target Datasource: Set the datasource for storing result dataset.
- Target Dataset: Select existing region or CAD dataset to store new region objects.
- New Dataset: Check the New Dataset box and set name to save new region objects in a newly created dataset.
- Delete Source Object: If the line object layer is editable, check this box to delete selected objects from source dataset.
- Click OK to complete the conversion from line objects to region features.

- Each line object generates a single region object. Composite line objects will generate composite region objects.
- Straight lines cannot be converted to region objects. If selected line objects contain straight lines, the output window will prompt that the straight line objects failed to convert.
