To create a grid of Carlson points over an existing surface in Carlson Survey (with AutoCAD, IntelliCAD or OEM), follow
these steps:
1. Create a surface from the surveyed points
2. On the longest side, ensure you have a polyline (on it's own, not joined)
3. Surface > Spot elevations > Draw Spot Elevations. Use the settings shown below
4. Click OK then choose the surface created in 1
5. Click on the longest side PL
6. Enter in the space between points
7. Enter in Number of Left (or right) offsets. i.e. if you had a space of 100m wide and wanted a row every 5m, enter
in 20
8. Enter in the space between points (normally the same value entered in Step 6)
9. Leave the rest at 0 (if you're using Left offsets)
This will create a grid of Carlson points that will interpolate the elevation from the selected surface file.
