DXF workflow guide
Turn OpenStreetMap-derived context into a layered DXF
Choose a real area, export the useful context layers, then open a true-scale DXF in the CAD or vector application you already use.
Useful for
CAD users, urban designers, illustrators, students and anyone who needs editable geographic context
You will make
A layered DXF containing the selected open-data context—such as building footprints, roads, water, land use, vegetation and terrain—positioned at true scale.

From open map data to editable linework
- 1
Choose an area with a clear purpose
Open the example below or draw your own boundary around the site, corridor or district you need. Select only enough surrounding context to make the drawing useful: a smaller region stays faster to generate and easier to edit.
- 2
Select DXF and the layers you need
Choose DXF in Config, then include buildings, roads, water, terrain, land use or vegetation according to the drawing. Excluding unused layers makes the result more legible before it ever reaches CAD.
Use the job configuration as the source of truth for included layers, units and export settings when handing the file to a collaborator.
- 3
Generate, download and inspect the named layers
Submit the job and download the DXF once it succeeds. Open or import it using the displayed units, keep source layers separate, and inspect a few known streets and buildings against a current aerial or authoritative reference.
- 4
Adapt the linework for the destination drawing
In AutoCAD, Rhino, Vectorworks, Illustrator or another DXF-capable tool, simplify, restyle, crop or trace the exported context for the intended drawing. Preserve the original as a reference layer rather than overwriting it.
- 5
Replace information that must be authoritative
Use the file as fast, editable geographic context. Verify property lines, proposed work, critical dimensions, current construction and any engineering or survey information from project-authoritative sources.
Open-data limits
Check the context before you design against it
- OpenStreetMap-derived features reflect local mapping coverage and contributor updates; completeness and currency differ substantially by place and feature type.
- Building footprints, road classifications, land use and vegetation are useful context but may be generalized, incomplete or differently interpreted than your project conventions.
- Building heights are often estimated or absent, so treat massing as contextual rather than surveyed.
- The DXF is editable geographic context, not a cadastral, survey, engineering, BIM or construction document.
