When you create a surface, the surface may be empty and therefore is not visible in the drawing. However, the surface name is displayed in the Prospector tree so you can perform other operations, such as adding data.
| Create a new surface or import a surface | Create an AutoCAD Civil 3D TIN surface from a point file, define a boundary for the surface, and then force the surface triangulation along linear strings. |
| Review the surface editing operations | Expand the surface item in the Prospector tree to display its data. |
| Add/edit surface data | Edit operations are added to a surface definition. |
| Review the surface definition | A surface definition is a collection of a surface’s build, data, and edit properties. |
| Manage the surface | View and change the surface and its data. |
