Point File Format Dialog Box

Use this dialog box to view or edit the properties of a user point file format, which is used to import points from or export points to an ASCII (text) file.

File Information

Format Name

Specifies the name of the point file format. This name appears in the Point File Formats list in the Settings tree. Enter a name.

Default File Extension

Specifies the default file extension of the point data file when you import or export points using this format.

Enter a file extension or select one of the following:

• .auf: Autodesk Uploadable File, comma delimited. Required values in the file are Point Number, Northing, Easting, Level, and Description (in that order).
• .csv: Comma Separated Value file; ASCII (text) file comma-delimited.
• .nez: Northing, Easting, and Level data
• .pnt: Point file.
• .prn: Formatted text, space delimited.
• .txt: Delimited ASCII (text) file.
• .xyz: Coordinates X, Y, and Z.

Comment Tag

Specifies how descriptive text is designated in the point data file. Enter the symbol that precedes a comment in the point data file. For example, if you specify # for the comment tag, any line in the point data file that begins with #, such as #Autodesk Point Data, is ignored during import.

The comment tag indicates where the comment begins. A comment always ends at the end of the line.
