IGES file viewer
Open, inspect and measure IGES or IGS files in your browser.
How it works
Open
Drop an IGES or IGS file.
Inspect
Rotate, zoom and measure the model.
Export
Download an STL, share the model or request a quote.
What you can do
Measure
Measure faces, edges, holes, angles and overall size.
Weight
Choose a material to calculate volume and weight.
Parts list
Hide or isolate bodies in a multi-body model.
STL export
Download the model in millimetres or inches.
Share link
Share a 30-day browser link. No account required.
Manufacturing price
Get an instant estimate or send the part for engineering review.
What is an IGES file?
IGES (.iges or .igs) is a neutral CAD format for exchanging curves and surfaces. Some files contain open surfaces rather than a closed solid.
Use STEP when available. It preserves solid models more reliably.
Supported formats
Every tool accepts the same file types.
| Format | Extensions | Opens as |
|---|---|---|
| STEP | .step, .stp | 3D solid: view, measure, draw and export |
| IGES | .iges, .igs | 3D solid or surface: view, measure and export |
| STL | .stl | 3D mesh: view and measure |
| OBJ | .obj | 3D mesh: view, measure and export |
| SOLIDWORKS | .sldprt | Converted to STEP |
| Autodesk Inventor | .ipt | Converted to STEP |
| CATIA V5 | .catpart | Converted to STEP |
| Creo / NX | .prt | Converted to STEP |
| Parasolid | .x_t, .x_b | Converted to STEP |
| ACIS | .sat | Converted to STEP |
| Rhino | .3dm | Converted to STEP |
| DXF | .dxf | 2D drawing: view, measure and price |

FAQ
Is my file uploaded to FabDigit?
Yes. We upload it over an encrypted connection to open and price it. Only FabDigit and people with your share link can access it.
Can I get a price?
Yes. We price eligible parts instantly. Other parts go to an engineer for review. You can change the material, finish and quantity before ordering.
IGES or STEP: which should I send a shop?
Use STEP when possible. It preserves closed solids more reliably.
Can I share the model?
Yes. Copy a private link that works for 30 days. No account or software is required.
Can it open SOLIDWORKS, Inventor and CATIA files?
Yes. We convert supported part files to STEP, usually in under a minute. Without an account, you can convert 5 native files per day. Sign in for more.
Is it free?
Yes. No account or installation is required.
