Smooth Boundary

The Boundary | Edit Boundaries | Smooth command adds vertices to a selected polyline or polygon. Smoothing is accomplished by specifying a number of vertices and a tension value. MapViewer uses this information to determine a series of segments that approximate the area or curve. The Smooth Boundary command can only be used on a one selected polyline or polygon at a time.

 

Spline Smooth Boundary Dialog

You can add points and a tension factor in

the Spline Smooth Boundary dialog.

 

Current Points in Selection

The Current points in selection indicates the current number of vertices in the selected object.

 

Smooth to Box

The Smooth to box controls how many points are added by the smoothing process. The number represents the total number of vertices in the smoothed object. The default value for the Smooth to field is 10 times the original number of points.

 

Tension

The Tension value is a number between 0 and 1. The tension value determines the amount of smoothing to take place. A low tension value tends to exaggerate the amount of curvature in a selected object, while a high tension value produces a smoothed object with a minimal amount of curvature exaggeration.

 

The Preview button allows you to see what the selected object looks like after smoothing. Use this button to quickly view the affects of different tension values on an object.

To create the smoothed object, press the OK button. To go back return to the original object's shape, click the Cancel button.

The curve on the left contains four vertices. The curve on

the right is the same curve, smoothed using 40 vertices.
