SVG to DXF: check drawing units
For a wrong-size SVG-to-DXF export, check the drawing units and measure a known edge in the saved DXF before changing the scale.
Open the saved drawing
- Upload your supported SVG to the SVG to DXF converter.
- Click Generate DXF.
- Click Download DXF, then open that saved file in LibreCAD.
Use a source dimension you can verify. My sample declares a width of 60 mm and a height of 30 mm. You can repeat the check with the source SVG and downloaded DXF.
Measure between endpoints
In LibreCAD 2.2.1.6, I used File > Open to load the DXF and Auto Zoom to bring the rectangle into view.
- Choose Tools > Info > Distance Point to Point.
- Enable Snap on Endpoints.
- Pick the rectangle's top-left and top-right corners. Read the distance in the command output.
- Pick the top-right and bottom-right corners to measure the height. Press Escape when finished.
Compare each reading with the intended source dimension, using the same units. If a reading differs, keep the original export and record the source size, drawing-unit setting and measured distance before editing a copy. This run did not reproduce or repair a scale mismatch.
What the downloaded sample showed
On November 6, 2026, I converted the sample in headless Chrome 156.0.8078.80. The download finished at 11:04 UTC. I then opened that actual saved file in LibreCAD and measured it manually.
| Check | Observed result |
|---|---|
| Input SVG | 161 bytes; declared size 60 × 30 mm |
| Downloaded DXF | 401 bytes |
| LibreCAD horizontal distance | 60.0000 |
| LibreCAD vertical distance | 30.0000 |
| Independent saved-file readback | 60 × 30 drawing units; $INSUNITS = 4 (millimeters) |
| Rectangle properties | Closed checked |
| Deliberately open interior line | Closed unchecked |
The separate file check used ezdxf 1.4.5. Its readback record contains the saved vertices and closed flags. I double-clicked each contour in LibreCAD to inspect its Closed checkbox, then canceled the dialog without changing the geometry.
What remains untested
I tested this straight-edged, millimeter-based sample only. I did not test inch imports, other CAD or CAM programs, curves, physical cutting, kerf or finished-part accuracy. I also did not test a repair workflow for an incorrectly scaled drawing.
