Importing Point Files that Contain User-defined Properties


Import point files using point file formats that contain user-defined properties.

When you import an ASCII point file, user-defined attributes described in the point file format are mapped to the user-defined properties in the survey database. If a matching property does not exist then it is created.

The user-defined attribute data for the points is stored as extended data using the same attribute data system as the LandXML extended properties. These properties are managed on the Survey tab in the Manage Extended Data collection in a survey database.

In the Manage Extended Properties dialog box, on the Survey Points node there is a new right-click menu option to Insert Into Drawing. When you use this option it forces the creation of the Survey-defined extended properties in the current drawing.

When new attributes are created in the survey database during an ASCII point file import, the data type of the drawing side attribute is replicated in the survey database, for example, Station would map to Station. Also, when attributes are mapped back to the drawing, the data type is preserved. For more information, see Managing Survey Extended Properties.


To import point files that contain user-defined properties

  1. In Toolspace, on the Survey tab, right-click the survey database collection New Local Survey Database. Enter a name
  2. Right-click the new database Manage Extended Properties.

    Importing the LandXML Property definitions before you create new user-defined properties can save time because the LandXML property definitions may match the requirements for the additional properties. For more information, see Extended Property Definition Files.

  3. Define properties for the Survey Points. Expand the Survey Point node, right click User-DefinedNew. For more information, see Creating and Editing User-defined Properties.
  4. When you have completed creating the Survey Point user-defined attributes, in the Manage Extended Properties dialog box right-click Survey PointsInsert Into Drawing.
  5. In Toolspace, on the Settings tab, expand the Points collection and create a new Point File Format that uses the new attributes you created in step 3. When you set the column name in the Point File format, verify that the user-defined properties you created are prefaced with “Point.”. For more information, see Understanding Point File Formats.

    When you have completed creating the user-defined properties and the new point file format, save the drawing as a new drawing template. You can use this template when you want to import points into the survey database using the customized point file format.

  6. Import a point file using the Import Survey Data wizard or the Import Points command. For more information, see Importing Point Files.
