Expand1. Create an Materials coverage using domain extents.
|
- Create a new coverage with the AdH "Materials" type.
Expand1. Duplicate the mesh domain coverage and change it to the AdH Material coverage type.
|
- Use the Duplicate command on an existing coverage. This will copy any feature objects on the coverage.
- Use the Rename command to give the coverage a new name.
- Change the coverage type.
|
|
Expand2. Digitize material areas (polygons).
|
- If needing to create addition polygons for material areas, follow the steps below:
Expand1. Create additional arcs for material polygons.
|
Expand1. 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.
|
Expand2. Modify arcs.
|
- Feature arcs often need to be edited after initial creation.
Expand3. Split arcs.
|
- An existing arc can be split by:
Expand3. 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.
|
|
|
|
|
Expand3. Define material types.
|
- Right-click on the materials coverage and select the Materials List and Properties command.
- In the Materials List and Properties dialog, add materials to the material list and assign Manning's n values to each material. If desired, change the fill display properties (color and texture) of each material.
|
Expand4. Assign materials to polygons in the materials coverage.
|
- Using the Select Feature Polygons tool, select a polygon and use the Assign Material command.
- In the Assign Material dialog, assign the material using the drop down menu.
