Notes from the workflow
Clear explanations for the details that matter.
Field formats, careful checks, and more useful handoffs.
Diagnose point import problems by checking the format definition, columns, delimiters, identifiers and drawing context before changing coordinates.
Prepare a defensible design/as-built comparison with confirmed point pairs, signed coordinate differences, inclusive tolerances and retained exceptions.
Download synthetic point tables, design and measured pairs, a revision example, slope observations and a small TIN with explicit expected outcomes.
Understand PNEZD, PENZD, NEZ, CSV, TXT and Excel point tables. Check axes, delimiters, identifiers and units before exchanging survey data.
Review axes, units, precision, tolerances, planar calculations and original-TIN methods. Understand what the results establish and what they do not.
Resolve a Northing/Easting order mismatch with an asymmetric control, an explicit column map and a checked export rather than moving the points.
Review the reference, method and complete output for your source data.
