Line To Region

Function Description

Convert the selected line object to a region object, and save to a region dataset or CAD dataset.

When converting a line object to a region object, a closed line object is converted into the boundary of a region object; an unclosed line object is converted into the boundary of a region object after connecting end-to-end. As shown in the figure below, Figure 1 shows converting a closed line object to a region object, and Figure 2 shows converting an unclosed line object to a region object.

Figure 2: Converting an unclosed line object

Access

  • Edit Data tab -> Object Editing group -> Type Conversion > Line to Region

Instructions

  1. Open the line dataset in the map. In the current line layer's selectable state, select one or more line objects.
  2. In the Edit Data tab, click the Type Conversion dropdown menu, then click the Line to Region button to open the Line to Region dialog box.
  3. In the dialog box, select the target datasource and dataset for storing the newly generated region objects. There are two ways to save the result data: save to an existing dataset or create a new region dataset. The parameters in the dialog box are as follows:
    • Target Datasource: Set the datasource where the result dataset will be saved.
    • Target Dataset: Select an existing region or CAD dataset to store the newly generated region objects.
    • New Dataset: Check the New Dataset check box, set the name of the new dataset, and save the newly generated region objects to the new region dataset.
    • Delete Source Object: If the selected line object layer is editable, you can check the Delete Source Object check box to delete the selected objects from the source dataset.
  4. Click the OK button to complete the conversion of line objects to region features.
Notes:
  • One line object generates one region object; a combined line object generates a combined region object.
  • Straight line cannot be converted to a region object. If there is a straight line among the selected line objects, the output window will prompt that the straight line object failed to convert.
