Technical note

Before you convert JML to DWG

Geospatial coordinates are absolute positions on the earth, and they are large: a projected easting runs to six or seven digits, while latitude and longitude are small decimals. DWG expects a drawing laid out near its own origin in millimetres or inches. The geometry itself converts correctly, but it can land tens of kilometres from 0,0, or arrive at a scale where an entire county is forty units across. Zoom to extents first, then measure one known distance before dimensioning anything.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as JML 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.

The proliferation of niche formats like DWG creates unnecessary hurdles. After wasted hours on forums, I discovered this lean converter that delivers single-purpose excellence—precisely the 'no nonsense' solution CAD beginners require.

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 inherited a mess of DWG files from a previous engineer – all in different versions. reaConverter batch‑converted them all to a single, clean DWG format (2018) with no errors. It even fixed some corrupt headers. This tool is a miracle worker.

FAQ

JML to DWG Conversion

What are JML files?

JML is the native vector format of OpenJUMP, a free GIS written in Java. The name stands for JUMP Geographic Markup Language, and the file is a text document in XML that stores one map layer: its points, lines, and polygons, together with a table of attributes for each object, such as names, numbers, and dates. It is a simplified variant of the GML standard, with the difference that the description of the attribute fields is placed at the beginning of the file itself, so the file can be opened without any extra template or schema. OpenJUMP grew out of JUMP, a project of Vivid Solutions, the authors of the widely used geometry library JTS, and JML files are still the easiest way to save and share layers between OpenJUMP users.

What are DWG files?

DWG (which stands for "Drawing") is a proprietary format of AutoCAD, a program widely used for creating engineering and architectural projects. The format is also a default extension used by several other computer-aided design (CAD) pieces of software, including IntelliCAD, Caddie or DraftSight. DWG files contain complex design structures including several layers, which can be 2-dimensional or 3-dimensional.
