Additional Information
Duplicate of BUG-000111780: The point data used for the terrain is regularly spaced - as if from a raster rather than LiDAR or photogrammetric points. Regularly spaced points create problems for Delauney triangulation because they are co-circular, and triangles can form using one diagonal or another between four co-circular points and still be valid. It is not deterministic. This causes inconsistent triangulation along the boundaries of neighboring tiles during processing resulting in contours that do not always match across tile boundaries. A workaround for this is interpolating terrain to raster using natural neighbors interpolator which is not sensitive to which way triangle diagonals are formed with co-circular data and contouring of the raster.Workaround
Create a raster surface from the terrain or point file, and use the Surface Contour tool.
