Nathan_UK Posted July 31, 2018 Share Posted July 31, 2018 (with the help of this forum) I have taken the site contours survey data and created a 3D terrain. I have been trying (for quite some time now!) to use the site modifier tool to create a pad (excavate the terrain) to install a slab and more. My issue has been that the z value of the terrain does not match the actual value of the terrain as dictated by the survey data. When I have drawn the pad, the z value (which should then be the lowest point of the slab) should be 165.6 (metres above sea level) where-as the elevation I have to input to get it anywhere close is -5600. How do I adjust the terrain Z value to accurately reflect the correct values. Many thanks for your time. Quote Link to comment
Boh Posted August 1, 2018 Share Posted August 1, 2018 The DTM z heights should match your survey source data. Could you post your file so I can have a look? Quote Link to comment
