You can use commands to import point data, export point data, and transfer point data between files.
Importing points is a quick way to place points into a drawing. For example, if a surveyor collects point data using a data collector, the data can be downloaded from the collector as an ASCII (text) file and then imported into an AutoCAD Civil 3D drawing.
Before you can import, export, or transfer point data, you must specify a point file format for each file that point data is read from or written to. The point file format describes how the point data is stored in the file. You can use the point file formats that are supplied with AutoCAD Civil 3D or create your own formats.
Use a point file format to describe how point data is arranged in a file when you import, transfer, or export points.
Use the Point File Formats collection in the Settings tree to create and manage point file formats.
Use a dialog box to view or change the properties of a point file format.
Use some columns in a point file format to perform calculations, such as adjusting the elevation values.
Use the Settings tree to manage point file formats. You can share a point file format and print a list of the point file formats in a drawing.
Create two types of point file formats: a user point file format and a user point database format.
Use the Settings tree to access formats you want to change or delete.
Import point data from an ASCII (text) file or a Microsoft® Access .mdb file into a drawing.
Before you import point data from an ASCII (text) file that contains user-defined columns you must create a User-Defined Property Classification.
Export drawing points to an ASCII (text) file or a Microsoft® Access .mdb file.
Use point file formats to transfer point data from one format to another and to convert the coordinate system of a set of points.
