Extract text from SmartSketch drawings (IGR)
To convert IGR drawings to another format, you need SmartSketch or other Cad software.
To convert other file formats to the "2D Drafting Document" file type, you need software like SmartSketch or a similar tool.
The .IGR file format is primarily a SmartSketch Drawing file. SmartSketch is a 2D drafting and design software originally developed by Intergraph and now owned by Hexagon. These files store vector graphics, dimensions, annotations, and parametric constraints used heavily in process, power, and marine engineering. Users often need to convert .IGR files because they are highly proprietary. Viewing or editing them usually requires an expensive, specialized license for SmartSketch. They cannot be natively opened in web browsers, standard office suites, or popular 2D CAD programs like AutoCAD without a specific export step.
For sharing and collaboration, it is best to convert .IGR to universally accepted formats like PDF for viewing and printing. If the drawing needs to be edited in other CAD tools, DXF or DWG are the ideal targets. Be aware that parametric constraints and proprietary metadata might be lost when moving from .IGR to a generic DXF file.
Because .IGR is a closed, proprietary format often relying on the Microsoft Compound file architecture or ZIP compression, standard online converters usually fail to process it. Exact geometry and constraint logic can often only be perfectly read by the original software. If our analysis detects a supported underlying format, viewing or conversion may still be possible. Less common uses for the .IGR extension include Igor Engraver music files and Quest3D layouts, but these are very rare.
Convert.Guru analyzes your IGR file, detects the exact format, and lets you read the text inside.
Users also converted PRJ, OCT, MI, ED and MAJ files.
If you want to convert IGR file to MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS, ALAC, APE or WV, you can use SmartSketch or similar software from the "2D design and drafting" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to IGR, try SmartSketch or another comparable tool in the "2D design and drafting" 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 IGR converter.
