Convert TEK to another file type
To convert your TEK file to another format, you need Tekton or other Cad software.
Convert a file to TEK
To convert other file formats to the "Structural Engineering Data" file type, you need software like Tekton or a similar tool.
About TEK files
The .tek extension is a prime example of a "filename collision," where a single extension is used by completely unrelated industries, creating confusion for users trying to open them. Most frequently, a .tek file is a proprietary structural analysis project created by LH Logismiki for their Tekton software, a tool widely used in Europe for earthquake-resistant building design. These files contain complex vector data, reinforcement details, and 3D structural models. The frustration here is high: standard CAD viewers like AutoCAD or SketchUp cannot parse this proprietary binary format, meaning you often need the specific, licensed software just to view a floor plan.
In a completely different context, .tek serves as a legacy Geotechnical Data Transfer standard used in Finland. These files store soil investigation data, drilling resistance logs, and sounding results. Unlike the CAD files, these are often ASCII-based, but their rigid formatting makes them difficult to import into modern GIS systems like ArcGIS without a dedicated parser. Finally, you might encounter this file as an encrypted navigation map from an Ecovacs robotic vacuum, which is effectively a "black box" data blob.
Conversion Recommendations:
For Structural Projects (Tekton): If you need to edit the geometry in another program, the native software is required to export to DXF or IFC. If you simply need to archive or share the engineering drawings, printing the layouts to PDF/A is the most reliable method to preserve line weights and annotations.
For Geotechnical Data: Since these often contain raw data points, the best target is CSV or XLSX. This allows you to visualize the soil parameters in Microsoft Excel or standard graphing tools.
For Robotics: These files are generally not convertible for human use and serve only as backup/restore points for the device hardware.
Convert.Guru analyzes your TEK file, detects the exact format, and lets you read the text inside.

The TEK Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our TEK converter.
