Opening STP files
Did your computer fail to open a STP file? We explain what STP files are and recommend software that we know can open or convert your STP files.
What is a STP file?
Files that contain the .stp file extension normally hold 3D assembly files in a 3D product model data exchange format. These files contain three-dimensional object data. STP files can be supported by a variety of different mechanical design programs.
The files that contain the .stp file suffix are normally saved in a text-based ASCII format containing STEP ISO application protocols. These files are often used to exchange 3D data between different CAD systems.
The .stp file format is also by the Adobe Acrobat Exchange software. The Adobe software uses the .stp file extension for Acrobat Exchange plug-ins that allow a user to add additional features to the software application.
Software that will open, convert or fix STP files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
