Step by step

How It Works

reaConverter offers the fastest, simplest solution for converting your B files into DWG without GIS software - all files processed on your PC for maximum privacy and speed.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as B and end up in DWG. reaConverter turns the layers into drawing entities in batch, so a full project folder moves across in one run.

  • Convert every layer in a folder to DWG with the same settings
  • Go the other way too, from DWG to Shapefile, when the GIS team needs the drawings back
  • Render the same data to PDF for a quick review copy
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

After nearly two years of relying on online converters, I finally installed standalone software. Why didn't I do this sooner? Now I can work completely offline — no more wasted time uploading/downloading or eating through my data allowance!

I needed to convert DWG to DXF for a laser cutter, and reaConverter did it flawlessly. The geometry remained intact, and the line weights were preserved. I've tried free tools, but they always mess up arcs. This is the only one I trust.

If you work with AutoCAD, Autodesk, or similar CAD software, you’ve likely faced format compatibility issues. Every developer seems to insist on their own proprietary formats, making conversions a real challenge. The solution? reaConverter. This tool effortlessly handles two-way conversion between dozens of specialized formats!
