Convert DXF to SVG in Inkscape
Use a version-appropriate Inkscape import, inspect the DXF entities and units, save an SVG copy, and measure a known dimension before handing it off.
Open the DXF in Inkscape, choose the import units deliberately, inspect the imported objects and save an SVG copy. Reopen the SVG and compare a known dimension, holes, separate parts and orientation. A successful import does not prove that every entity, curve or target application is supported.
Prepare the DXF and record its contract
Keep the original DXF unchanged and record its declared or intended units, entity types, known width and height, holes and separate parts. If the file came from a machine workflow, preserve that context outside the SVG copy.
This tutorial uses a self-made R14 calibration file with straight edges, a hole, an island and a notch. It is a bounded geometry example, not a test of every CAD entity, block, text object, spline or custom unit setting.
Import and save an SVG copy
Open a copy in Inkscape
Open the DXF in a separate document or copy of the source. Note the import dialog's unit choice and preserve the original file for comparison.
Inspect the imported objects
Select the drawing and inspect whether paths, holes and separate parts arrived as expected. Do not treat a thumbnail or a successful open as proof that every entity survived.
Measure a known dimension
Use the document or selection tools to measure a known width or height. If the result is wrong, stop and diagnose units before saving an SVG copy.
Save the SVG separately
Save a new SVG file and keep the DXF beside it as the source record. Avoid overwriting the DXF or silently converting unsupported objects into an unverified shape.
Reopen and compare
Close and reopen the SVG, then compare the known dimension, holes, separate parts, orientation and visible curve or line representation with the source contract.
Download a bounded R14 fixture
The downloadable DXF is the recorded 100 × 70 mm straight-edge fixture used for import and read-back checks. The companion SVG is a geometry reference, not a claim that Inkscape will preserve arbitrary DXF content.
Use the verification record to identify the project fixture and its expected dimensions. Text, blocks, splines, curves and target-software behavior remain outside this example.
Diagnose an import before editing geometry
| Symptom | Next check |
|---|---|
| Everything is 25.4 times too large or small | Compare the DXF unit assumption with the import unit and measure the same known dimension before rescaling. |
| Some entities are missing | Identify the missing entity type and test a supported export or editor; do not infer support from one simple path. |
| Holes or separate pieces changed | Compare closed paths, fill and object grouping with the source contract; preserve the original before repairing. |
| The SVG looks right but measures wrong | Reopen and measure the saved SVG, then check viewBox, width/height and physical units before handoff. |
Continue with the receiving format check
Use the existing SVG-to-DXF guide for the reverse direction, the format guide for a handoff decision, and the SVG size diagnosis when physical units disagree. No page here replaces a target editor or machining acceptance test.
