Зачем конвертировать 3DM в IGES?
IGES is the interchange format accepted by older industrial CAD, CAM, and toolpath systems that may not support Rhino's native format or STEP. Engineers request it when milling software or legacy CAD packages list .IGES as their only neutral import option. For modern targets - SolidWorks, Creo, Inventor - STEP is usually cleaner, but when the receiving party specifically asks for IGES, this conversion delivers it.
Способы конвертации 3DM в IGES
Rhinoceros - File > Export Selected PAID
Open the .3dm file, select geometry, choose File > Export Selected, and pick IGES (*.igs) - the most reliable path for trimmed NURBS models.
Autodesk Fusion 360 FREE
Open the .3dm via File > Open, then export as IGES (.igs) - the free personal tier supports IGES export.
FreeCAD OPEN-SOURCE
Import the .3dm via File > Open, then export as IGES using File > Export - free and cross-platform.
Command line - FreeCAD CLI
Run FreeCADCmd convert.py with a short Python script that opens the .3dm and calls Part.export([...], 'output.iges').

- IGES carries only NURBS curves and surfaces - mesh objects, block definitions, layers, materials, and annotations are not included in the output.
- Trimmed surfaces can develop small gaps or open edges after import; run your target application's geometry heal or repair tool before using the model for machining.
- STEP (
.stp) is the preferred neutral format for modern CAD - choose IGES only when the receiving software specifically requires it.
Часто задаваемые вопросы
Can I convert 3DM to IGES without Rhino?
.3dm and exports IGES, and FreeCAD is a free open-source alternative. For large or complex models, Rhino gives the most predictable results.
