Opening SEC files

Did your computer fail to open a SEC file? We explain what SEC files are and recommend software that we know can open or convert your SEC files.

What is a SEC file?

The SEC file format was developed by Parametric Technology Corporation for one of their CAD (Computer Aided Design) tools. These SEC files are classified as data files that are generated through the Pro/ENGINEER software, which was also created by Parametric Technology Corporation. Also known as Pro/ENGINEER sketch files, these .sec files contain graphics, layout parameters and other formatting attributes that have been saved by the user for a project in the Pro/ENGINEER software.

These SEC files store sketches and drawings made by a user in the Pro/ENGINEER software. This application is designed for Windows PCs. The Pro/ENGINEER software is also known as Creo Elements/Pro. These Pro/ENGINEER sketch files are affixed with the .sec extension.

An SEC file can be opened and viewed using the Pro/ENGINEER software. These .sec files can also be edited and updated through this CAD program. There are no known tools that can be used to export these .sec files to other standard bitmap graphics file formats.

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.
