It would be very nice if more extend options will be avaliable in Csurvey.
I have a survey where several big chambers had been surveyed as a polygon along the walls and I'd like to exclude these shots form the profile.
In Therion I can use 'extend hide' or 'extend ignore' to do this but in Csurvey only 'extend left' and 'extend right' are avaliable.
Maybe there are other ways to do this which I am not aware of.
