WebDXF Editor
Trim geometry, annotate lengths, and resave DXF files directly in the browser for quick QA or macro testing.
Open utility
What it does​
Open DXF files in the browser, trim or measure entities, and save changes back to DXF without round-tripping through heavy CAD. Ideal for quick QA, macro testing, or touch-ups before sending geometry downstream.
When to use it (and when not to)​
Use it when:
- You need to trim stray lines or add quick measurements without launching desktop CAD.
- You are testing CAD macros and want to verify DXF output.
- You want an offline DXF sanity check before sharing with vendors.
Avoid it when:
- You need 3D modeling, constraints, or advanced drafting features.
- Your file is extremely large or hatch-heavy and would benefit from a full CAD workstation.
Inputs and outputs​
Inputs​
| Input | Description |
|---|---|
| DXF file | Upload the drawing you want to inspect or edit. |
| Layer visibility or colors | Toggle layers to focus on critical geometry. |
| Selection and snap mode | Pick how you select and measure lines. |
| Units reference | Use the source DXF units or your own reference scale. |
Outputs​
| Output | Format | Notes |
|---|---|---|
| Edited DXF | DXF | Save the updated geometry locally. |
| Measurement readouts | On-screen | Lengths and distances for quick QA. |
How to use​
- Load your DXF file into the editor.
- Toggle layers or snaps to isolate the geometry you need.
- Trim, annotate, or measure as required.
- Review the drawing on-screen for accuracy.
- Download the updated DXF.
Example dataset: Open flange.dxf, trim stray construction lines, measure the bolt circle, and save the cleaned DXF.
- Expected output: Returns a cleaned DXF plus on-screen measurements you can reference in QA notes.
Accuracy and verification​
- Designed for DXF workflows; keep a backup of the original before overwriting.
- Large files may feel slower in-browser than on a workstation.
- Units follow the source DXF; verify scale if you import from mixed-unit sources.
- All edits stay local; export to keep your changes.
FAQ​
- Which DXF versions are supported? Works with common R12+ DXF geometry.
- Does it support blocks and hatches? Simple blocks work; heavy hatches may be slower and should be checked after export.
- Are edits stored online? No. Files never leave your browser.
- Can I change units? Use the scale reference in your DXF; the tool respects the source geometry.
- Will it keep layer names? Layer data is preserved when you resave.
