OpenStreetMap to DWG (AutoCAD) converter
Upload your OpenStreetMap file and get DWG, which opens in AutoCAD in a couple of minutes: osm2cdr reads the geometry of your file and hands you a ready DWG straight away. Processing runs on our servers, the result is ready to download as soon as it finishes, and files up to 50 MB are supported. And if you have no file of your own, or need a fresh map of an area, osm2cdr builds DWG straight from the OpenStreetMap map: you simply pick an area on the map, choose the DWG format and download the result with up-to-date OSM data — with layers for buildings, roads, water and features.
How OpenStreetMap differs from DWG
| Format | Extension | Type | Purpose |
|---|---|---|---|
| OpenStreetMap | .osm / .pbf | OSM geodata | Map source: roads, buildings, POI, boundaries |
| DWG | .dwg | CAD | Architectural design, master plans, construction documentation, land surveying |
How to get DWG on osm2cdr
- 1Select an area on the map on the osm2cdr home page
- 2Choose the DWG format and, if needed, a style and CRS
- 3Click Export and download the ready DWG file

When you need DWG
The main scenario is simple: you already have a OpenStreetMap file — upload it and osm2cdr returns DWG, ready to use in a dedicated program (editing, printing, analysis, embedding in a project). The alternative is for when you have no file at hand or need a fresh map of an area: the same DWG is then built straight from up-to-date OpenStreetMap data for your chosen area, split into layers for buildings, roads, water and features.
What changes when going OpenStreetMap → DWG
Drop in a OpenStreetMap file and osm2cdr reads its geometry and returns DWG; and with no file of your own, the same DWG is built straight from the OpenStreetMap map for your chosen area. Either way the data model changes. Here the first source is connected OpenStreetMap geodata: tagged buildings, roads, water and features. The map is built straight to DWG, with no loss on an intermediate OpenStreetMap file: geometry is laid out across named drawing layers (buildings, roads, water), coordinate accuracy is kept, and attribute tables are not carried into DWG — the result is meant for CAD work, not attribute analysis.
Upload your OpenStreetMap extract → DWG
Upload your OpenStreetMap extract — an .osm or .pbf dump — in the form above and osm2cdr will convert it to DWG for you. Files up to 50 MB are supported. If your file is too large, or you just want a fresh map of an arbitrary area, you can skip the upload entirely: pick an area on the home page and download DWG with up-to-date OSM data right away.
Import OpenStreetMap into AutoCAD
To import OpenStreetMap into AutoCAD you need neither a plugin nor a live connection between AutoCAD and OpenStreetMap: pick the area here, export it as DWG and open the file in AutoCAD like any other drawing. Layers come named and separated — buildings, roads, water, landuse — in metric coordinates, so OpenStreetMap data lands in AutoCAD ready to work with.
OpenStreetMap and KML to AutoCAD: three ways
A ready drawing from this page is not the only route. The guide compares three: a DWG export from the map builder, import in AutoCAD Map 3D and Civil 3D, and QGIS with ogr2ogr — plus KML and KMZ to DWG.
FAQ: OpenStreetMap → DWG
Can I upload my OpenStreetMap file?
Yes, now you can: upload your OpenStreetMap file right on this page and osm2cdr will read the geometry and convert it to DWG. Files up to 50 MB are supported. If the data comes from OpenStreetMap, you can skip the upload entirely — we'll export the map straight into DWG.
Is it free?
Yes, exporting an OpenStreetMap map to DWG on osm2cdr is free. Select an area, the DWG format and download the result.
Which programs open DWG?
The DWG format opens in dedicated programs for its category. See the DWG format page for the full list and details.
Why is this better than an online OpenStreetMap → DWG converter?
An online converter caps the result quality at the quality of the source OpenStreetMap file. osm2cdr takes data from the OpenStreetMap source and builds DWG with correct layers directly — with no loss on an intermediate OpenStreetMap file.
How do I import OpenStreetMap into AutoCAD?
Pick the area on the map, export it as DWG and open the file in AutoCAD, DWG TrueView or BricsCAD. No OSM file and no plugin are needed — osm2cdr builds the drawing from OpenStreetMap for you, with layers already separated.
Can I connect AutoCAD to OpenStreetMap directly?
Plain AutoCAD geolocation only gives you a map background, not editable geometry. AutoCAD Map 3D and Civil 3D can import raw OSM data, but you have to fetch the file and set the layers up yourself. A DWG export skips both steps: named layers, metric coordinates, ready to draw on.
