Use our free tool to view your 3D STEP CAD files online without needing to install any specialist 3D viewing software. Our STEP viewer tool will generate a real-time 3D preview of your STEP file with pan and zoom controls, allowing you to see your 3D model from any angle.
Our STEP viewing tool can load most STEP files, and we are working on improvements all the time to improve compatibility and enhance rendering quality. If you are looking to convert your 2D image files to 3D files such as STL then we have a 2D to 3D conversion tool here.
First, click the "Upload..." button and select the STEP file you wish to view. Once your STEP file has been received it will be displayed in your browser.
We aim to process all STEP file viewing requests as quickly as possible, this usually takes around 5 seconds but can be more for larger or more complex files so please be patient.
We aim to create the most accurate rendition of your STEP file with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the STEP file you submit. The generated preview file within your browser is deleted after 15 minutes,
Yes! Our STEP file viewer will run on any system with a modern web browser. No specialist software is needed to use our file viewing tools.

The STEP file format is a 3D format defined in 1994 and used to store 3D objects for use in computer-aided design (CAD) applications. STEP files are text-based, formatted files containing one instance per line.
Although STEP files are widely supported by most CAD applications, the format does have its limitations, such as the necessity to read the complete file into memory in order to parse the contents, and due to the textual storage of information, the files can be quite large.
