5 Best Free IGS File Converter Software for Windows

Here is a list of Best Free IGS File Converter Software for Windows. IGS or IGES, stands for Initial Graphics Exchange Specification, is a 3D file format that is used to store 3D models and data. Using the listed freeware, you can convert an IGS file to various other 3D file formats. The most commonly supported output 3D file formats include STEP, STL, OBJ, 3DS, DXF, PLY, and DAE. All these software support import and then export approach to perform the conversion. So, you can simply open an IGS model, view the model, and then export it using the dedicated function.

These are basically CAD software that also provide a lot of design tools, like mesh designing tools, add predefined 3D shapes, extrude, translate, rotate, scale, etc. Hence, you can edit IGS model prior to conversion. You can use a variety of features to visualize IGS file such as orthographic view, perspective view, rotate, zoom, rendering style, measuring tool, statistics, and more. Also, many converters also support external plugins to further enhance their functionality. All in all, these are feature-rich CAD designing software that also work as an IGS file converter.
