What is XYZ Survey, Delaunay TIN Contours & GIS-to-DXF Studio?
XYZ Survey & GIS-to-DXF AutoCAD Export Studio converts topographic point lists (Matricule ; X ; Y ; Z) and geographic files (KML, KMZ, GPX, GeoJSON, CSV) into structurally validated AutoCAD Release 12 (AC1009) ASCII DXF drawings complete with declared layers, 3D POINT/LINE/POLYLINE entities, ID/elevation TEXT labels, and $EXTMIN/$EXTMAX header extents.
How to use XYZ Survey, Delaunay TIN Contours & GIS-to-DXF Studio in 3 steps
- 1
Paste or import an XYZ survey table or GIS vector file
Handles semicolon, comma, tab, or space delimiters and normalizes decimal commas automatically.
- 2
Configure CAD layers, text height, breaklines, or target EPSG
Separate points, point IDs, and elevations onto dedicated AutoCAD layers and reproject lat/lon to metric UTM/Lambert.
- 3
Verify AC1009 structure and download .dxf
Review the coordinate table, skipped-row report, and live DXF entity validator before downloading.
Key features and benefits
- Writes $EXTMIN and $EXTMAX header extents so AutoCAD, Civil 3D, QGIS, and LibreCAD open framed on your survey.
- Normalizes European comma decimals (370412,45 -> 370412.45) that break legacy XYZ-to-DXF scripts.
Common use cases
Importing total-station or GNSS rover Matricule;X;Y;Z text exports into AutoCAD / BricsCAD.
Projecting WGS84 KML/GeoJSON parcel boundaries into 1:1 metric UTM DXF polylines.
Why browser-based works better
XYZ Survey, Delaunay TIN Contours & GIS-to-DXF Studio consolidates related gis, surveying & cad studios workflows into one cohesive, multi-mode browser studio — eliminating tab-hopping across fragmented single-purpose tools.
Every mode executes locally using Web APIs and audited client-side libraries, so private files, tokens, and source code never leave your device.
