Subset

On the Design tab, in the Utilities group: Select General | Subset String to subset a string file into open and closed strings. The function can be used to validate strings, or identify strings that can be used in a wireframe cut operation.

Set the following parameters in the String Subset form:

File

Choose an input file type. Double-click (F3) in the File box to select the name of the input file that contains the strings you want to subset.

East, North, Z

Double-click (F3) to identify the Easting and Northing and (optionally) Z coordinate fields in the input file.

String field

(Optional) Double-click (F3) in the String field box to identify the field containing values that define whether data points will be joined by a line. The values of this field in successive records must be the same before the points will be strung.

Join field

(Optional) Double-click (F3) in the Join field box to identify the field that will contain values that define whether data points will be joined by a line i.e. strung. If successive records have the same value in this field and no String field is defined, a line will join the points. If a String field is defined, then values in each field in successive records must be the same before the points will be strung.

Subset Options

Select from the available options to include closed strings, open strings, and single point strings in the output file.

Output file

Choose an output file type and double-click (F3) to select the name of the output file.

Run

Finally, click the Run button to run the function.
