IGES to STL

Convert IGES or IGS surface geometry into a millimetre STL mesh, then inspect it in your slicer.

Model workspaceIGES / IGS → STL

Your model goes here.

Choose your file or try the original sample below. No installation or sign-up.

01 / HOW IT WORKS

Open, inspect, then use your result.

  1. 01

    Open your file

    Choose, drop or paste your IGES file. All three input methods use the same local checks.

  2. 02

    Look from every angle

    Orbit, zoom and switch between standard views. Read the dimensions and object count beside the model.

  3. 03

    Download the converted file

    After conversion, download STL. Open the result in your destination software and check the units before use.

02 / TRY IT YOURSELF

A real file. A result you can check.

This original four-hole plate measures 80 × 50 × 8 mm. The sample uses the input format for this page. Use the default unit and axis settings to reproduce those dimensions.

03 / FORMAT & USE

IGES to STL

Prepare supported CAD surfaces for a mesh workflow. Check the solid count and open-surface report before printing.

What this viewer supports

Standard text IGES/IGS only: up to 32 MiB and one million triangles. Tessellation uses a 0.05 mm deflection setting; verify approximation accuracy downstream. Colors, layers and annotations are not retained. No surface repair.

Supports files up to 32 MiB, 1 million triangles and 2,000 mesh objects. For larger assemblies, export only the parts you need.

04 / QUESTIONS

Know your input. Understand your output.

Will conversion make an open surface printable?

No. Conversion does not cap holes or repair topology. STL loses CAD surfaces, units metadata and colors; coordinates are written in millimetres.

Do I need an account or credits?

No. These tools are free and run in your browser. No account, subscription or credits are required.

Is my model uploaded?

No. Your selected file is read and processed in this browser. The page downloads its CAD engine and public samples, but does not upload your model. Refreshing or leaving the page clears the current file from the tool.

How are units and orientation handled?

Dimensions use millimetres with Z up. GLB uses metres with Y up; exported STL is mm/Z-up and OBJ is mm/Y-up.

Can I paste a file from my computer?

Copy a file in your file manager, then paste here. Your browser must expose the clipboard as a file; a copied path or text will not open a model.
