Adjacent Point Connection Line

Function Description

Adjacent Point Connection Line: During connection, the start and end points of lines are not considered. It judges based on the distance between the endpoints of line objects, connecting the endpoint of the first line to the nearest endpoint of another line object. The direction of the resulting line after connection is the same as that of the first line object.

  • The Joint Line Object function applies to 2D line layers and CAD layers.
  • The Joint Line Object function is only available when line objects are selected.
  • This operation does not apply to complex objects and compounds. For an introduction to object types, please refer to Object Overview.

Function Entry

  • Edit Data Tab -> Feature Editing Group -> Line Editing -> Connect and Break -> Adjacent Point Connection Line

Operational Instructions

In the Adjacent Point Connection Line dialog box, you can set the operation method for each field separately, or select multiple fields simultaneously for unified settings. Below is an explanation of this dialog box.

  1. With the layer in an editable state, select one or more line objects to be connected.
  2. In the Edit Data tab, under the Line Editing drop-down menu, click the Adjacent Point Connection Line button in the Connect and Break group to execute the line connection operation.
  3. The corresponding Adjacent Point Connection Line dialog box pops up. In this dialog box, set the attributes of the new object after the connection is completed.
    • Edit Layer: The Edit Layer drop-down list displays all editable layers in the current map. You can click the drop-down arrow on its right side to select the layer to operate on.
    • Field List Area: This area lists the information of all non-system fields and editable system fields in the current editable layer, including the field, type, and the operation method for the new object's field after the connection operation is completed. By default, the field attributes of the first object are used.
    • Operation Method Setting Area: Provides four operation methods.
      • Is Empty: Refers to the value of this field for the new object being empty after the connection is completed.
      • Sum: Refers to the value of this field for the new object being the sum of the corresponding field values from each connected object after the connection is completed.
      • Weighted Mean: Refers to the value of this field for the new object being the weighted mean value of this field from all connected objects after the connection is completed. A weighting field needs to be specified. If no weighting field is selected, its simple average is calculated, which means adding up the selected field values of all source objects and then dividing by the number of source objects.
      • Save Geometry: Refers to the value of this field for the new object being the same as the value of this field from a currently selected object after the connection is completed. You can click the drop-down arrow on the right to choose the object properties value to be used by the new object.
  4. Click the OK button to complete the line object connection operation.
