Function Description

The Object Editing group on the Object Operation tab provides functions to handle boundary lines of Line or face geometry pairs. The curve smoothing function mainly smoothes the boundary line of Line or Region to turn the polyline into a continuous smooth line object.

The controls in the Object Editing group are available only when there are selected Geometry (Line and Region) in editable layers in the Map.

• The Smooth function is used to smooth the boundary line of Line or Region in the editable layer selected in the current Map.
• Smoothness is the degree to which the original line object is made smoother. The value of this parameter is proportional to the number of nodes in the changed line object. Its value type is integer, and the value range is 2-10.
• For an explanation of the principle and results of curve smoothing, see: Description of the smooth method .
• Line objects that participate in Smooth Line must be line objects with 3 or more nodes. Because a two-point straight line is a smooth line, there is no need for Smooth Line.

Function entrance

• Object Operation tab-> Object Editing group drop-down box-> Smooth.

Operating instructions

1. Make the Layer Settings of the Geometry (Line or Region) to be smoothed in the Map editable.
2. Select the Geometry (Line or Region) to be smoothed. You can press and hold the Shift or Ctrl key at the same time to select multiple geometries continuously.
3. On the Object Operation tab, in the Gallery control in the Object Editing group, click the Smooth button to pop up the Curve Smoothness Setting dialog.
4. Enter a value for curve smoothness in the text box to the right of Smoothness. The default value is 4.
5. To smooth Geometry on other layers in the Map, repeat steps 1 through 4 above.
6. Click the OK button to complete the curve Smooth Line for Select Objects.
