In AutoCAD Civil 3D, you can create, work with, and manage points using a variety of commands and tools.
The points created by AutoCAD Civil 3D are called Coordinate Geometry (COGO) points, which are very different from AutoCAD point nodes. AutoCAD point nodes have only coordinate data (XYZ values) associated with them. However, COGO points, in addition to coordinate data, have a variety of properties associated with them, including point number, point name, raw (field) description, and full (expanded) description. Unlike AutoCAD point nodes, which exist in a single drawing, COGO points can be stored in a project outside a drawing and referenced by multiple users. In AutoCAD Civil 3D, the term point refers to a COGO point, not to an AutoCAD point node.
You can group related points into point groups using a variety of criteria. You can use point groups to control the appearance of points in a drawing, to create surfaces, or to export selected points to a file. For more information, see .
Use a project to manage and protect the points needed for a design project. When you use a project as a central repository for your project points, the points can be viewed and copied by others, but not necessarily modified.
