SMS:TUFLOW 1D Project Workflow

This workflow includes specific workflows needed in creating a general 1D TUFLOW project.

To build a 1D TUFLOW model in SMS, use the following:

1. Start with a 2D TUFLOW project.
See the TUFLOW Project Workflow for more information on building a 2D TUFLOW project.

2. Set up a 1D network.

1. Create a TUFLOW 1D Network coverage. Create a new coverage with the TUFLOW "1D Network" type. 1. Create new coverage from scratch. Select Map Data in the Project Explorer and use the New Coverage right-click command. Use the New Coverage dialog to create a new coverage by selecting the desired coverage type, and naming the coverage. 2. Create new coverage from an existing coverage. 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. 2. Create a centerline arc. Create a series of arcs in the 1D Network coverage to represent the centerline. 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. 1. Create additional vertices on arcs. Use the Create Feature Vertex tool to add vertices along arcs. 2. Refine the arc shape. Use the Select Feature Vertex tool and the Select Feature Node tool to move/edit existing arcs and refine the shape by dragging the nodes/vertices.
