Before creating or importing points, specify the settings that control how the points are numbered and how point number collisions are handled.
If you import points from an external file, and the points in your point data file do not have point numbers, use the Point Identity settings to control how the points are numbered as they are imported.
If you import points from an external file, and the points in your point data file have point numbers, specify how point number conflicts are resolved if the point file contains a point number that already exists. The following example shows how the If Point Numbers Already Exists settings resolves conflicts when your point data file contains a point number that already exists:
Example: If you have a point in the drawing with the following properties:
You import a point data file containing a point with the same point number, but different properties, as follows:
If you set the If Point Number Already Exists setting to Overwrite before you import the point file, the point in the drawing becomes:
Number: 23 Northing: 502.18 Easting: 498.65 Elevation: blank Description: blank
All properties are overwritten, even properties that aren’t defined in the point data file, such as elevation and description.
If you set the If Point Number Already Exists setting to Merge before you import the point file, the point in the drawing becomes:
Number: 23 Northing: 502.18 Easting: 498.65 Elevation: 70.5 Description: IP
The number, northing, and elevation are overwritten, but the elevation and description in the drawing are preserved.
