Why we like it

Super3D ships .igs as a separate single-format add-on from its .iges bridge, so it's worth picking up only if the three-letter extension actually shows up in your workflow. It earns its place in the superhive library as a focused option for pipelines that pattern-match on the extension.

What is Super3D Import & Export .Igs?

The .igs format carries the same CAD interchange data as .iges, using the older three-letter extension still required by some vendor pipelines and DOS-era tooling. Super3D Import & Export .Igs targets mechanical and engineering workflows, whether you need to match a supplier's filename pattern or open old IGES exports saved with the .igs extension.

On import, you pick a .igs file from File → Import → Super3D: IGS (.igs); the add-on uploads it to the Super3D conversion service, then downloads and merges the result into your active scene. Surfaces are tessellated to mesh and hierarchy is preserved, with the same caveats as IGES — no PMI, and surfaces may need fill-holes repair. On export, the scene writes to OBJ on the main thread, then converts to .igs via Super3D and saves to disk.

Because conversion runs in the cloud, Blender stays lightweight and no separate CAD interchange install is required. The add-on carries GPL licensing, and a portion of each order goes to the Blender Foundation.

Who is Super3D Import & Export .Igs best for?

Super3D Import & Export .Igs is best for mechanical and engineering pipelines that require the three-letter .igs extension, vendor handoffs matching a supplier's filename pattern, and recovering old IGES exports saved as .igs.

How much does Super3D Import & Export .Igs cost?

Super3D Import & Export .Igs is completely free to download and use.

Frequently asked questions

What's the difference between .igs and .iges in this add-on?

Super3D Import & Export .Igs handles the same CAD interchange data as .iges, just with the older three-letter extension. The three-letter form predates Windows long-name support, and some tools and scripts still pattern-match on it, which is why it ships as a separate product from the .iges bridge. If both extensions appear in your real workflows, you might want both; otherwise pick the one your pipeline needs. The conversion itself is identical either way.

Which Blender versions does Super3D Import & Export .Igs support?

Super3D Import & Export .Igs is tested on Blender 4.2 through 5.1, and its legacy bl_info entry covers Blender 4.0 and up. It's packaged as a focused add-on carrying GPL licensing. Beyond a compatible Blender version, the only requirement is an internet connection, since conversion runs through the Super3D cloud service rather than on your own machine. Check the developer's page for the current details before installing.

Do I need to install a separate CAD interchange tool to use Super3D Import & Export .Igs?

Super3D Import & Export .Igs runs its conversion in the cloud through the Super3D service, so you don't need any separate CAD interchange software installed locally. All you need is Blender and an internet connection. This is also what keeps Blender lightweight — the heavy conversion work happens on the service side rather than in your session. The add-on adds import and export entries directly to Blender's File menu once installed.

Can I run Super3D Import & Export .Igs alongside other Super3D format add-ons?

Super3D Import & Export .Igs can be installed alongside other Super3D format add-ons without conflicts. Each format ships as a separate extension with its own ID and operator names, so they don't collide inside Blender. If you work with multiple formats, Super3D also offers an Extra Format Bridge that bundles every supported format together, though the .igs product is a focused single-format slice for pipelines that only need that one extension.
