To Import Point Data

Import point data from an ASCII (text) file or a Microsoft® Access .mdb file into a drawing.

Importing points, such as survey point data collected by a data collector, is a quick and effective way to place points into a drawing.

Before you import points, you must create a point file format that describes the layout of the point data in the point data file.

Important: The highest point number allowed in Civil 3D is 4,294,967,295. You can use point names or User Defined Properties to reference numbers greater than 4,294,967,295. For more information, see Using Custom Properties with Points.

For more information, see Understanding Point File Formats and Creating Point File Formats.

You can add the imported points to a point group, make adjustments to the data as it is imported, including elevation adjustments, coordinate transformation, or coordinate data expansion, encounter how the imported points are numbered as they are created.
