Clip to Polygon

On the Design tab, in the Utilities group, select Clip | Clip to Polygon to isolate strings that are inside or outside a given polygon. While the interactive clipping function uses the viewing plane to define how the clipping is performed, in this case a "best fit data plane" is calculated from the clipping polygon (if there are multiple polygons then the first is used).

On the Input tab of the form, select the file containing the strings to be clipped and specify the required fields in the Input file.

File

Select a file type and double-click (F3) to select the file containing the strings to be clipped. If required, define a filter to selectively control the records to be processed.

Easting and Northing and Z fields

Specify the names of the fields in which Easting, Northing, and (optionally) Z coordinates are stored in the input file.

String field

(Optional) Specify the name of the field containing values which 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

Specify the name of the field containing values which 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.

Tip: On the Design tab, in the Editing group, you can also clip the open or closed strings in a Vizex display layer. See: Clip
