IGES is one of the oldest neutral CAD exchange formats, dating back to 1980. It represents models as surfaces and curves rather than watertight solids, and although STEP has largely replaced it, IGES files remain everywhere in legacy archives, tooling data and supplier exchanges.
USDZ packages Pixar’s Universal Scene Description into a single uncompressed ZIP for Apple’s AR Quick Look. An iPhone or iPad can open a USDZ link directly into augmented reality from Safari — no app required — which makes it the format for AR product previews on Apple devices.
| IGES | USDZ | |
|---|---|---|
| Geometry | B-rep surfaces & curves | USD mesh scenes |
| Units | Yes, embedded | Meters (implied) |
| Colors & materials | Limited | PBR materials |
| Animations | No | Yes |
| Typical use | Legacy CAD exchange | Apple AR Quick Look |
Yes — free with no accounts, no watermarks and no file-size limits. Conversion runs on your own machine, so there are no server costs behind it.
No. The converter runs entirely in your browser using WebAssembly. Your .iges file never leaves your device, which makes it safe for confidential designs.
IGES stores exact CAD surfaces, which are tessellated into triangles at a quality you choose — from fast drafts to near-exact precision meshes. Preview the result in the built-in 3D viewer before downloading.
Yes. Every converted model opens in the built-in 3D viewer with an assembly tree, display modes and section views, so you can inspect the result first.
IGES stores exact boundary surfaces, but every output available here is a triangle mesh. Tessellation is irreversible: feature history, constraints and analytic curves cannot be recovered from the converted file. The USDZ result contains the converted geometry and flat colors, but no source textures, rigs or animation tracks.
IGES and STEP both move CAD data between systems, but they are generations apart. When IGES still appears, why STEP usually wins, and how to convert both for free.
What do tessellation quality settings actually control? Linear and angular deflection explained with practical presets for 3D printing, rendering and web delivery.
Most online CAD converters upload your intellectual property to unknown servers. Learn what actually happens to uploaded files and how client-side conversion avoids the risk.
