Understanding STEP and IGS file formats

STEP and IGS are both file formats used in the field of computer-aided design (CAD). STEP (Standard for the Exchange of Product model data) files, with the extension .step or .stp, are used to represent 3D objects in a standardized way, allowing for easy sharing and collaboration across different CAD software. IGS (Initial Graphics Exchange Specification) files, with the extension .igs or .iges, are also used for representing 3D models but are based on an older standard. IGS files are widely used for exchanging information between different CAD systems.

Why convert STEP to IGS?

Converting STEP files to IGS can be necessary when working with older CAD systems that do not support the STEP format. By converting to IGS, you ensure compatibility and maintain the ability to share and edit 3D models across various platforms.

Best software for STEP to IGS conversion

Several software options are available for converting STEP files to IGS. One of the most reliable and widely used is Autodesk Fusion 360. This software provides a comprehensive suite of tools for CAD design and supports a wide range of file formats.

How to convert STEP to IGS using Autodesk Fusion 360

  1. Open Autodesk Fusion 360 and import your STEP file by clicking File → Open and selecting the STEP file you wish to convert.
  2. Once the file is open, navigate to File → Export.
  3. In the export dialog, choose IGES as the file format.
  4. Click Export to save the file in the IGS format.

Alternative software options

Other software that can perform STEP to IGS conversion includes SolidWorks and FreeCAD. Both offer similar functionality and can be used if you do not have access to Autodesk Fusion 360.
