OK, I have added two new options for import command and changed the survey structure policy. Now non-existing surveys are created. + import -filter <string> -- only stations with given prefix and shots between them will be imported - prefix will be removed from station names + import -surveys (create)|use|ignore -- specifies how to import survey structure. create = split stations into subsurveys, if subsurveys do not exists, create them use = split stations into existing subsurveys ignore = do not split stations into sub-surveys This option works only for .3d import. So now you can do following survey terikan import terikan.3d -filter terikan ... scraps & maps ... endsurvey You can download developer's snapshot to test them. S.
