User:Jcreer/SMS:3D Bridge

A 3D bridge can be modeled on an existing model using components. To model a 3D bridge, the following is needed:

• Area Property coverage
• Two arcs on the Area Property coverage defining the upstream and downstream sides of the bridge
• Top, upstream, and downstream profiles

Also, having an existing mesh, scatter set, or grid of the site is typically helpful.

To build a 3D bridge, do the following:

1. Create an Area Property coverage.
2. Create arcs representing the upstream and downstream side of the bridge location.
3. Right-click in the Project Explorer and select New General Component | Bridge.
4. Link the Area Property Coverage to the component in the Project Explorer.
5. Right-click on the component item and select Edit Bridge.
6. In the Bridge dialog, define the top profile, upstream profile, and downstream profile.
7. Export the 3D bridge and save out the XMUGRID file.
8. Import the XMUGRID file.
