БЫСТРЫЙ ОТВЕТ
Возможно ли конвертировать 3DM в IGES?
Да - 3DM конвертируется в IGES.

Вы можете сделать это прямо здесь с помощью нашего бесплатного конвертера - регистрация не нужна, и ваш файл будет удален сразу после завершения.

Upload your file with the converter above - it is free and files are deleted after converting. For complex trimmed surfaces, Rhinoceros or Autodesk Fusion give the most reliable output. The key caveat: only NURBS geometry transfers; mesh objects in the model will be missing from the result.

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').

Об этих форматах

Качество и на что обратить внимание

  • 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?
Yes - Autodesk Fusion 360 (free tier) imports .3dm and exports IGES, and FreeCAD is a free open-source alternative. For large or complex models, Rhino gives the most predictable results.
Will the IGES file open in SolidWorks, Creo, or Inventor?
Yes, all three import IGES. For complex trimmed solids, STEP typically causes fewer healing issues - use IGES only when the recipient specifically requests it.
Are `.igs` and `.iges` the same format?
Yes, both extensions refer to the same IGES format - choose whichever the receiving software expects.
Why does my imported IGES have open edges or gaps?
IGES export tolerances may not match the receiving application's import tolerance. Run the geometry repair or import diagnostics tool in your CAD software to close small gaps.
