Technical note

BYN to DWG: 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. 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. BYN is made of pixels and DWG 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 DWG 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 BYN to begin with.

Map Data Workflow

From map data to a working drawing

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

I previously used a similar program that stopped working, so I needed to find a replacement. reaConverter turned out to be the perfect solution—after reviewing the instructions on this page, I was able to convert DWG files immediately.

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.

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!

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!

FAQ

BYN to DWG Conversion

What are BYN files?

BYN is a binary grid format developed by the Canadian Geodetic Survey of Natural Resources Canada (NRCan) to distribute geoid models and height conversion grids, such as CGG2013a and HT2_0. A file of this type stores a regular grid of geoid heights, which allows ellipsoidal heights obtained from GNSS measurements to be converted into heights above the Canadian Geodetic Vertical Datum of 2013 (CGVD2013). The file consists of an 80-byte header and a data section. The header gives the grid boundaries and spacing in arc-seconds, the size of each value, and a scale factor, while the data section holds whole numbers instead of decimals, which keeps the file compact. Companion files with the .err extension use the same structure to describe the accuracy of the model.

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.

Can reaConverter convert BYN to DWG?
