You can divide a polygon into two smaller polygons by drawing a link between two nodes that define the polygon. You can also remove a boundary between two polygons and combine them into one polygon. You can specify the centroid to remove. Splitting and combining polygons change the centroid, the area, and perimeter values.
To divide a polygon into two smaller polygons
- Open the drawing where the polygon topology was created and load the topology.
- In Map Explorer, right-click the topology name. Click Divide Polygon.
- Specify a node for the first divide point.
- Specify the node for the second divide point.
To merge two polygons into one polygon
- Open the drawing where the polygon topology was created and load the topology.
- In Map Explorer, right-click the topology name. Click Merge Polygon.
- Specify the link (boundary between two polygons) to remove.
- Specify the centroid to remove.
- On the command line, type Y to merge the polygons.
