Home Conversions IGES to FBX
IGES → FBX Convert IGES to FBX Turn an IGES CAD model into an FBX mesh. Curved surfaces are meshed finely enough to stay smooth, and the part keeps its real size and orientation.

What is IGES? IGES is an older CAD exchange format that stores exact curves and surfaces. Many machines, CAM systems and older CAD packages still expect it.
Full name Initial Graphics Exchange Specification Type Exact CAD geometry Used in Mastercam, Rhino, SolidWorks, CATIA, older CAM software Strength Accepted by legacy CAD and CAM tools. Limits Older than STEP; solids are often stored as loose surfaces. More about IGES What is FBX? FBX is Autodesk's scene format for games and animation. It carries meshes, materials, hierarchies and animation, and it is the usual way to bring models into Unity and Unreal Engine.
Full name Filmbox (Autodesk) Type 3D scene (meshes, materials) Used in Unity, Unreal Engine, Maya, 3ds Max, Blender, MotionBuilder Strength The default import format for game engines. Limits Closed specification; versions differ between programs. More about FBX
Good to know IGES stores exact surfaces; FBX needs triangles. We mesh each surface with a deviation of 0.05% of the part's size, which keeps holes and fillets smooth for printing and rendering.
Dimensions stay in the units of the original file, usually millimetres.
Questions Will curves look faceted? No. Curved faces are meshed with a tight tolerance, so holes and fillets stay smooth.
Does it keep the size of my part? Yes. The mesh has the same dimensions as the CAD model.
Are my files uploaded? No. Everything runs in your browser.
