Smooth

The Object Editing group on the Object Operations tab provides a function to process boundaries for line or region geometric objects. The smooth function is mainly used to smooth boundaries for line or region geometric object, turning the polyline into a smooth line object.

Controls in the Processing group are only active when there are selected geometric objects (line or region geometric objects) in editable layers in the map window.

Instructions

• Smooth the lines or the boundary lines of regions.
• The smoothness indicates how smooth the line or the boundary of the region will become. It is proportional to the number of vertices. It is an integer raging from 0 to 2147483647. The relationship between the smoothness and the number of the vertices is shown as below.

• For the smooth principle, see Smooth Methods.
• The line object involved in the smooth operation must have more than three nodes (including three). Because the straight line between two points is already smooth.

Basic Steps

1. Set the layer in which you want to smooth objects editable.
2. Select the line or region objects to smooth.
3. Click the Object Operations tab > Object Edit Gallery > Object Operations group > Smooth button to open the Smooth Settings dialog box.
4. Input a smoothness value in the text box Smoothness. The default value is 4.
5. Repeat step 1 to 4 to implement another smooth operation.
6. Click OK to finish the smoothness.

Note

You can smooth objects in multiple layers at the same time if the multilayer editing function has been enabled.
