- If needing to create addition polygons for material areas, follow the steps below:
1. Create additional arcs for material polygons.
|
1. Create feature arcs, nodes and vertices.
|
- In the Map module, create feature objects in the active coverage.
- Use the Create Feature Arc tool to create arcs in the map coverage.
- Begin creating a new arc by clicking in the Graphics Window at either arc end. If clicking on an existing feature node, vertex or arc, the new arc will snap to that object.
- Double-click or press the Enter key to terminate the arc.
- Use the Create Feature Node tool to create additional nodes alone or to split arcs.
|
2. Modify arcs.
|
- Feature arcs often need to be edited after initial creation.
3. Split arcs.
|
- An existing arc can be split by:
2. Add a node the arc.
|
- Use the Create Feature Node tool to add a node on an arc in order to split it into two arcs.
|
3. Add a new connecting arc.
|
- Use the Create Feature Arc tool to start or end a new arc on an existing arc to split the existing arc into two arcs.
|
|
4. Merge arcs.
|
- Two arcs that share an end node can be merged together.
- Select the shared node using the Select Feature Node tool.
- Right-click on the node and select the Convert to Vertex command to merge the arcs.
- If desired, the Select Feature Vertex tool can be used to select and delete the new vertex.

|
|
2. Build polygons for material areas.
|
- Polygons are not created automatically when arcs are enclosed. To create polygons:
- Use the Feature Objects | Build Polygons command.
