1. Create specified flow arcs.
|
- Create feature arcs in the specified flow location.
1. Create feature points, arcs, nodes and vertices.
|
- In the map module, create feature objects in the active coverage.
- Use the Create 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 Point tool to create additional nodes alone or to split arcs.
|
2. Modify arcs.
|
- Feature arcs, whether digitized or incorporated from a boundary condition or a material coverage, often need to be edited after initial creation.
1. Create additional vertices on arcs.
|
- Use the Create Vertex tool to add vertices along arcs.
|
3. Split arcs.
|
- An existing arc can be split by:
2. Add a node to the arc.
|
- Use the Create Point tool to add a node on an arc in order to split it into two arcs.
|
3. Connect the end of an existing arc to the middle of the arc.
|
- Use the Select Points\Nodes tool to drag the node of an existing arc to anywhere in the middle of another arc. This will split the second arc into two arcs.
|
4. Add a new connecting arc.
|
- Use the Create Arc tool to start or end a new arc on an existing arc to split the existing arc into two arcs.
|
|
|
|
2. Add specified flow properties.
|
- Using the Select Arc tool, right-click on the specified flow arc and select the Attributes Table command.
- Define the specified flow properties in the Attributes Table dialog.
