How do I convert an IGES file to DAE?

Upload your IGES file, select DAE as the output, adjust the mesh tessellation tolerance (e.g., 0.1mm) and coordinate units, then hit Convert. The tool automatically rebuilds NURBS surfaces as triangulated polygons and exports a COLLADA .dae file ready for import into Blender, Unity, or three.js.

Why should I convert IGES to DAE instead of using IGES directly?

DAE (COLLADA) is an XML-based interoperable format natively supported by game engines, WebGL, and DCC tools, while IGES is primarily an old CAD exchange format for NURBS surfaces. Converting lets you bring industrial CAD geometry into real-time 3D workflows with materials, texture coordinates, and a controlled polygon budget.

What happens to IGES layers, colors, and NURBS precision during conversion?

The converter tessellates IGES NURBS surfaces into polygons based on your chosen chord tolerance. Layer names are flattened into the DAE scene graph, but material color assignments and UV coordinates are preserved. Curves and points are discarded unless they are used as trimming boundaries. This means visual appearance is kept, but precise NURBS definitions are approximated.
