Free online IGES to SVG converter

When a browser, vector editor, or document workflow accepts SVG but not CAD exchange files, an IGES model may need a 2D view for sharing. SVG displays that view as scalable vector graphics, but it is not a replacement for the original 3D model.

What IGES is

IGES (Initial Graphics Exchange Specification) is a neutral CAD format used by engineers and manufacturers to exchange geometry between design applications. Files with .igs or .iges extensions can contain curves, wireframes, surfaces, and solid-model geometry.

What SVG is

SVG (Scalable Vector Graphics) is a format for two-dimensional graphics described with paths, shapes, and other vector elements. It scales without pixelation and is supported by web browsers and vector-editing software. It suits diagrams and projected CAD views, not editable 3D geometry.

Online on 101convert.com

1. Open the IGES-to-SVG converter on 101convert.com and upload an IGES file. You can add several files for batch conversion; the per-file size limit is shown on the page.
2. Start the conversion. The converter runs on the site’s server with FreeCAD.
3. Download the resulting SVG file or files.

Offline with desktop software

FreeCAD is free, open-source software for Windows, macOS, and Linux. It can import IGES geometry and export a TechDraw page as SVG. Create a drawing view first: exporting the 3D model directly as SVG would not preserve its 3D geometry.

1. Open the .igs or .iges file in FreeCAD.
2. Switch to the TechDraw workbench and create a page with TechDraw → Insert Page using Template.
3. Select the imported model in the tree and choose TechDraw → Insert View. Set the view direction and scale in the view properties.
4. Select the TechDraw page and choose File → Export. Select SVG as the file type, choose a destination, and save.

Quality and compatibility limits

The SVG contains a 2D projection, not the original IGES surfaces or solids. The chosen projection direction, scale, and hidden-line settings determine which edges appear. The result does not retain 3D depth or editable CAD geometry, and the SVG’s appearance can vary between applications.
