Delete

Delete command is used to delete positions of tie lines. In contrast to the Delete command from the Line pulldown menu, this command may not delete a tie line completely but only those positions that meet the defined settings.

Command

Effect

Selected position

The selected position of a tie line is deleted.

By line

Tie line positions of selected strip(s) are deleted.

By scanner

Tie line positions of selected scanner(s) are deleted.

By criteria

Tie line positions that fit to specified criteria are deleted.

Bad line numbers

Tie lines that do not match a trajectory line number are deleted. Trajectory line numbers are checked from the active trajectory directory in TerraScan.

Delete / By criteria

By criteria command deletes tie line positions that fit to specific criteria. The criteria are defined in the command's dialog. The dialog also shows the number of effected tie lines and tie line positions as soon as the criteria is specified. Only tie line positions that fit to all criteria set in the dialog are deleted.

To delete tie line positions by criteria:

1. Select By criteria from the Delete command of the Line pulldown menu.

This opens the Delete Positions by Criteria dialog:

2. Define one or several criteria for tie line removal.

The number of effected tie lines and tie line positions is displayed dynamically in the dialog.
