How can i remove or exlude all z=0.00000 from a TIN that is imported from a txt file?
I would assume the easiest thing to do would be to open your TXT file in Excel, sort by the Z value field and save, then recreate your surface.
Yes, I think i have to use notepad++ to do that.
Other way is to just use import point fist (with eg. Lee Mac Pointmanager) and than afterwards make ik a TIN.
I still find it hard to believe that points in a TIN can only be asjusted one at a time
