Step by step

How It Works

reaConverter offers the fastest, simplest solution for converting your ERR 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

Converting ERR to DWG usually means handing GIS data to someone who works in CAD. reaConverter makes that hand-off without a GIS seat on either side, for one layer or a whole delivery.

  • 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.
