Extract text from 3D models and PCB designs (3DI)
To convert 3DI Models and designs to another format, you need Cadence or other 3D software.
To convert other file formats to the "Game / EDA 3D Model" file type, you need software like Cadence or a similar tool.
A .3DI file typically contains a 3D model used in classic video games developed by NovaLogic, such as the Delta Force series. Alternatively, it serves as a highly specialized 3D output used by Cadence Design Systems for their 3D Design Viewer, representing complex Printed Circuit Board (PCB) layouts and electronic components in a three-dimensional space.
The main disadvantage of a .3DI file is its heavily proprietary nature. NovaLogic files rely on legacy, closed-source game engines that are no longer actively supported by modern 3D software. Cadence .3DI files contain dense, specific mechanical data that requires expensive enterprise software like Cadence Allegro to open natively. They are not supported by standard web browsers or general-purpose 3D modeling applications.
For a broader workflow, .3DI files should ideally be converted to universal formats. For game models, targets like OBJ or FBX are best. For Cadence PCB models, standard CAD formats like STEP (STP) or IGES are necessary. However, converting these files is incredibly difficult because the format is closed. Standard online converters almost always fail to parse the underlying geometry. Often, only the original software or specialized community modding tools can properly read or export the data.
Despite these restrictions, you can still analyze your file with convert.guru. Just drag and drop your file to identify the format, view its hexadecimal data, and convert it when possible. If our analysis detects a supported underlying or embedded format, viewing or extracting the content may still be achievable.
Convert.Guru analyzes your 3DI file, detects the exact format, and lets you read the text inside.
Users also converted STEP, GLB and SAT files.
If you want to convert 3DI file to [% faq_exts_to %], you can use Cadence or similar software from the "Proprietary 3D Model Storage" category. In the File menu, look for Save As… or Export….
To convert [% faq_exts_from %] files to 3DI, try Cadence or another comparable tool in the "Proprietary 3D Model Storage" category.
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 3DI converter.
