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 converted directly into 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

  1. Open the line dataset in the map. With the current line layer selectable, select one or more line objects.
  2. 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.
  3. In the dialog: select target datasource and dataset for storing new region objects. Two saving methods are available: save to existing dataset or create new region dataset. Parameters include:
    • Target Datasource: Specify the target datasource for result dataset.
    • Target Dataset: Select existing region or CAD dataset to store new region objects.
    • New Dataset: Check this box to create new region dataset, then specify its name.
    • Delete Source Object: When source line layer is editable, check this box to delete selected objects from source dataset.
  4. Click OK to complete conversion from line to region features.
Notes:
  • Each line object generates one region object; composite line objects generate composite region objects.
  • Straight lines cannot be converted into region objects. If selected line objects contain straight lines, the output window will indicate that the straight line objects failed to convert.
