Best for basic road geometry in an open CAD tool
License: Open source
Status: Unknown
- DWGDWG: opens and saves, partial fidelity. Needs the free ODA File Converter or LibreDWG; geometry and layers only
- DXFDXF: opens and saves, partial fidelity. 2D geometry, layers and text carry over; blocks and dimensions can lose detail
- PDFPDF: saves only, full fidelity. TechDraw pages export to PDF; PDFs cannot be opened for editing
- STLSTL: opens and saves, full fidelity. Mesh format
- STEPSTEP: opens and saves, full fidelity. Solid geometry exchange

Free and open source. Civil engineering support lives in community workbenches and is not a full replacement for a road design package.
2QG
Best for terrain, earthwork and LandXML data work
License: Open source
Status: Unknown
Free GIS that handles terrain and survey data well. It is not a design tool, so roads and grading stay manual.
