+frex3wv Posted July 10, 2009 Share Posted July 10, 2009 I have a pretty good idea (and picture in my mind) how the surveyors used equipment over horizontaly placed disks - but am unsure how they did readings for those set in the sides of buildings etc. Any info would be appreciated! Thanks in advance, Quote Link to comment
