Home Conversions IGES to DXF
IGES → DXF Convert IGES to DXF Turn an IGES CAD model into a DXF 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 DXF? DXF is AutoCAD's exchange format. We write your model as 3D faces that AutoCAD, LibreCAD and most CAD programs can open.
Full name AutoCAD Drawing Exchange Format Type Triangle mesh Used in AutoCAD, LibreCAD, DraftSight, laser and CNC software Strength Opens in AutoCAD-compatible software. Limits 3D faces only; not a solid model. More about DXF
Good to know IGES stores exact surfaces; DXF 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.
