Technical note

SIGDEM to DWF: what carries over and what does not

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. An SIGDEM file has a pixel count and a DPI value, and no real-world size at all. DWF is a drawing where one unit means one millimetre or one inch, so the conversion has to assign a scale. Set the DPI before the run rather than resizing afterwards, then measure one feature of known length in the output and scale the drawing once to match it. Everything downstream, from dimensioning to cutting, rests on that single check.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as SIGDEM 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'm a freelance CAD drafter, and DWF files are the bane of my existence. reaConverter converts them to DWG with editable geometry – I can finally modify old drawings without redrawing everything. Saved me a week of work on my last project.

As a long-time AutoCAD user, I was accustomed to working with DWF files. Transitioning to AutoCAD presented challenges — not just adapting to the new interface, but also converting legacy projects to the updated format. reaConverter handled the DWF-to-DWG conversions flawlessly, streamlining what could have been a tedious process.
