Technical note

How CUB and DWF differ in practice

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. DWF 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. CUB is made of pixels and DWF stores geometry, so the conversion traces the image into real lines, arcs and polylines. The result is editable in CAD: entities can be selected, snapped to and measured, rather than a bitmap wrapped inside a DWF container, which is what a viewer or a lightweight converter usually produces. It is still derived geometry, so expect contours rather than a structured drawing. Dimensions, blocks and meaningful layer names were never in the CUB to begin with.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as CUB and end up in DWF. 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 DWF 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.

I came here specifically to leave this review about reaConverter. I've been using it for seven months, several times a week - and it never crashes, freezes, or slows down my system. Best part? It's incredibly lightweight. Runs perfectly on just 4GB RAM and an Intel Core i3 processor. Conversions happen in a flash, and it works completely offline!

The online converters kept corrupting my DWF files, so I installed reaConverter. It's night and day – the conversion is fast, the quality is perfect, and it works offline. No more uploading sensitive project files to sketchy websites. Highly recommend for any engineer.

My company uses reaConverter daily to convert DWF files from our suppliers into PDFs for internal review. The batch mode handles 50+ files per day, and the quality is consistent. We've saved hundreds of hours compared to manual conversion in AutoCAD.

CAD files, vendor specs, legacy archives — everyone uses different formats. reaConverter's the only tool I trust to actually deliver usable PDFs from messy DWF files without corrupting layers.
