Export — output formats

Once the section has been computed, you can export to 4 formats: SVG, PNG, DXF, PDF. They live in the Export menu of the topbar.

SVG (Scalable Vector Graphics)

  • Vector format, can be reopened in Inkscape, Illustrator, browsers.
  • Keeps all geometry as separate objects: stratigraphic polygons, contact lines, boreholes, labels, patterns.
  • Typical size: 200-500 KB for a standard section.
  • When to use: include in editable reports for follow-up retouching (e.g. change colours in Illustrator without going back to the app).

PNG

  • High-resolution bitmap (default 200 dpi, configurable up to 600 dpi).
  • White or transparent background.
  • When to use: previews, PowerPoint slides, quick email attachments. For formal printing prefer PDF or DXF.

DXF (AutoCAD)

  • Standard CAD vector format, openable in AutoCAD, DraftSight, BricsCAD, LibreCAD, QGIS.
  • Separate layers for: topographic profile, stratigraphic contacts, water table, boreholes, labels, legend, polygons-by-layer.
  • Coordinates: in metres, local plane system (X = progressive abscissa on the section, Y = absolute elevation in m a.s.l.).
  • When to use: integrate the section in a CAD drawing of the project (e.g. urban plan, hydraulic-work design).

Paginated PDF

  • A4 / A3 / A2 / A1 page (selectable) with configurable title block:
  • header (project title, client, date, scale);
  • section at exact metric scale (e.g. 1:200, 1:500, 1:1,000);
  • stratigraphic soil table;
  • legend at the bottom;
  • company title block (logo + studio details).
  • When to use: final document for the technical report or as attachment to sub-soil reports.

PDF title-block configuration

The title block is set in File → Project settings → Title block:

  • Logo: upload PNG/JPG (suggested 300×100 px).
  • Studio details: name, address, VAT, responsible geologist.
  • Project details: work title, client, town, date, references.
  • Scale: set 1:200, 1:500, 1:1,000 or custom.
  • Orientation: landscape or portrait.
  • Margins: configurable in mm.

Studio details are saved in the browser preferences and reused on subsequent projects.

Coordinates and elevations in exports

All formats export the section with: - Origin at bottom-left (x=0, y=minimum elevation). - X increasing left to right (progressive abscissa on the trace). - Y increasing upwards (absolute elevation in m a.s.l.). - Units: metres.

For DXF this matters because other software (e.g. AutoCAD Civil 3D) expects coordinates consistent with the rest of the drawing.

  1. Generate the section (see Workflow).
  2. Configure the title block (logo, scale 1:500, A3 landscape).
  3. Export → Paginated PDF → download the PDF.
  4. Verify the scale by printing a test page: measure a known distance on the section and compare with the title-block scale.
  5. Attach the PDF to the technical report.

For a "live" version (CAD-editable) export DXF for the same project too and include it in the delivery package.
