If you work with CAD or 3D modeling, chances are you’ve come across step files. These files contain 3D data and are widely used for exchanging 3D models between different CAD systems. However, viewing step files can be a challenge if you don’t have the right software. Fortunately, there are several free online tools that allow you to view step files without the need for expensive software licenses. In this guide, we’ll explore the best options for viewing step files online for free.

One popular choice for viewing step files online is the GrabCAD viewer. This web-based tool allows you to upload and view step files directly in your browser. It supports a wide range of 3D file formats, including step, iges, stl, and more. The GrabCAD viewer also offers basic measurement and markup features, making it a versatile option for viewing and collaborating on 3D models.

Another great option is the Online 3D Viewer. This tool supports step files as well as many other 3D file formats, and it allows you to view and interact with 3D models in your web browser.
