Technical note

Before you convert GTX to DXF

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. DXF 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. A line in a GTX image is several pixels wide, so tracing it can mean different things and the mode is yours to choose. Centreline returns a single line running down the middle of each stroke, which is what a scanned drawing needs: one entity per line, snappable and dimensionable, rather than a long thin rectangle around it. Outline follows both edges and returns closed shapes, which suits clipart, logos and anything that will be filled or cut. A precision setting controls how closely the traced paths follow the pixel edges. One thing to plan for: vectorised output from this path is black and white, so colour in the GTX does not survive as colour in the DXF.

Map Data Workflow

From map data to a working drawing

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

In architecture, sharing DXF files with clients is impractical. reaConverter lets me create universally accessible PDFs in seconds—no more awkward 'Can you open this?' moments during presentations.

My laser engraver only accepts DXF, but my designs come in AI and SVG. reaConverter handles the conversion seamlessly – and preserves all the paths and cut lines. I've processed over 500 designs with zero failures. Absolutely indispensable.

This developer deserves industry recognition. What used to take hours in AutoCAD — converting 300+ DXFs to client-ready PDFs — now completes during a coffee break. Game-changing efficiency.

I can't begin to describe the hours I wasted trying to convert DXF to DWG online—it was pure time theft! When my boss handed me a flash drive demanding instant batch conversion (way outside my usual work), I suffered through two days of upload/download hell. A forum suggestion changed everything: reaConverter automated the entire process. Ten minutes later? Mission accomplished!

FAQ

GTX to DXF Conversion

What are GTX files?

GTX is a grid file used by NOAA's VDatum software to convert heights from one vertical reference to another. Heights on maps can be measured from different surfaces, such as the ellipsoid used by satellite positioning, the geoid that approximates mean sea level, or a tidal level like mean lower low water, and the difference between these surfaces changes from place to place. A file of this type covers an area with a regular net of points and stores the height difference at each of them, so that a program can add it to a measured height and obtain the value in the other system. Earlier versions were text files, while current ones are binary. The format is also used for global geoid models and for national height transformations.

What are DXF files?

DXF (Drawing Exchange Format) is a format associated with AutoCAD, a popular program used for computer-aided design by engineers, architects and other professionals in the field of building design and construction. The DXF format was developed in the early 1980s by Autodesk with the purpose of increasing the interoperability between AutoCAD and other CAD or advanced image design programs. It supports 2-dimensional and 3-dimensional drawings, and can be opened using a wide array of image processing programs.
