Convert IGS to another file type
To convert IGS 3D models to another format, you need SolidWorks or other Cad software.
Convert a file to IGS
To convert other file formats to the "3D Model Exchange Format" file type, you need software like SolidWorks or a similar tool.
About IGS files
An .IGS file is an Initial Graphics Exchange Specification file. It serves as a vendor-neutral format for exchanging 2D and 3D digital design data between different CAD (Computer-Aided Design) programs, using ASCII text to define wireframes, surfaces, and object models. You can open an .IGS file with almost any professional CAD software, including SolidWorks, PTC Creo, CATIA, and Autodesk Fusion 360. The main disadvantage of the .IGS format is its age and technical limitations. Created in 1980, it struggles with modern solid geometry. Because it translates shapes primarily as surface boundary representations rather than actual solid bodies, users frequently encounter broken models, missing faces, or unstitched edges when importing an .IGS file into modern CAD systems. The files are also uncompressed and can become massively inflated in size for complex models. To solve these geometry translation problems, you must convert the file. For robust solid modeling and modern CAD workflows, convert to .STEP (Standard for the Exchange of Product model data). For 3D printing or rapid prototyping, convert to .STL. For web use and 3D rendering, convert to .OBJ.
Convert.Guru analyzes your IGS file, detects the exact format, and lets you read the text inside.
If you want to convert IGS file to STEP, STL, DWG, DXF, PDF, OBJ, STP, FBX, DAE, 3DS, MAX or BLEND, you can use SolidWorks or similar software from the "Neutral CAD Data Exchange" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to IGS, try SolidWorks or another comparable tool in the "Neutral CAD Data Exchange" category.
The IGS Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our IGS converter.
