If you work with 3D models, chances are you've come across the .STP file format. This file format, also known as STEP files, is commonly used for storing 3D models and is widely supported by various CAD and 3D modeling software.

Unfortunately, Mac computers don't have a built-in STP file viewer, which can make it challenging to open and view STP files on your Mac. However, there are several third-party STP file viewers available for Mac that can help you easily access and view your 3D models.

One popular STP file viewer for Mac is eDrawings Viewer. This free software from SolidWorks allows you to open and view STP files on your Mac with ease. Simply download and install the eDrawings Viewer from the Mac App Store, and you'll be able to open and view your STP files effortlessly.

Another option for Mac users is FreeCAD, an open-source parametric 3D CAD modeler. FreeCAD supports the STP file format and provides a range of tools for viewing and editing 3D models. It's a great choice for Mac users who need a versatile STP file viewer that's also free to use.

If you're looking for a more feature-rich STP file viewer for Mac, you might want to consider using a professional 3D modeling software such as AutoCAD or Fusion 360. Both of these programs support the STP file format and offer advanced editing and viewing capabilities for 3D models.

In addition to these options, you can also explore online STP file viewers that don't require any software installation. Websites like A360 Viewer and GrabCAD allow you to upload and view STP files directly in your web browser, making it convenient to access your 3D models from any Mac computer.

Overall, there are plenty of options available for Mac users who need to open and view STP files. Whether you're looking for a free and simple STP file viewer or a more advanced 3D modeling software, you'll find a solution that meets your needs. With the right STP file viewer for Mac, you can easily access and view your 3D models without any hassle.
