What is an STP file?
An .STP file is primarily a STEP 3D CAD File used for 3D product model exchange. The format is defined by the International Organization for Standardization (ISO) under the ISO 10303 STEP standard. It stores 3D image data in a text format, making it easy to transfer 3D graphics between different CAD systems.
Because .STP has multiple possible meanings, it can also be a RoboHelp Stop List File by Adobe Systems, a SharePoint Template by Microsoft, or an Analysis Studio Project Information File by Appricon. We recommend using viewer.online/stp to identify the actual format of your file.
How to open STP files?
You can open standard .STP 3D files with major CAD programs like CATIA V5, FreeCAD, and Autodesk Fusion 360. If your file is a RoboHelp Stop List or a SharePoint Template, you need the respective software to open it.
Best practices and troubleshooting
If you need to share a 3D model with someone who does not have CAD software, you should convert the file. We recommend file conversion to sensible target formats on convert.guru. Excellent target formats for 3D printing or rendering include .STL, .OBJ, and .IGES.
Summary
viewer.online/stp analyzes .STP files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Ultimately, viewer.online/stp directly opens and previews .STP files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
