Feature Creation Tools Overview
Create features in the target layer Divide
Buffer
Copy Parallel
Union
Intersect
Create features in the same layer Split
Merge
1-20
Copyright © 1999–2001 ESRI. All Rights Reserved. ArcGIS
Divide
Creates features at a given interval along a line Can specify number or distance
Electric line
Target layer
Poles
1-21

Buffer
Buffers selected features by a specified distance
Two discrete polygons in target layer
1-22

Copy Parallel
Copies a line feature parallel to the original feature Positive is on the right side of the feature
Creates feature in target layer
1-23

Union and Intersect
Creates features in the target layer
Does not delete original features
Union Example: Creating a sales territory
Intersect Example: Overlapping area of sales territories
