Convert SMG to another file type
To convert SMG Composer files to another format, you need SOLIDWORKS Composer or other 3D software.
Convert a file to SMG
To convert other file formats to the "CAD Assembly Documentation" file type, you need software like SOLIDWORKS Composer or a similar tool.
About SMG files
The .SMG file extension is primarily a Technical Communication Assembly File created by SOLIDWORKS Composer. It is used to repurpose existing 3D design data for technical documentation, animations, and interactive 3D experiences. A smaller number of .SMG files are electrical panel label projects used by Tiflex Semiolog software. To open or edit these files natively, users require expensive licenses for SOLIDWORKS or CATIA. The .SMG format is highly proprietary and optimized strictly within the Dassault Systèmes ecosystem. This causes major bottlenecks in collaborative workflows because external clients or non-engineering teams cannot open the files without a specialized viewer or a costly subscription. Standard web browsers and generic 3D viewers cannot render them. Converting .SMG files is often necessary to share 3D documentation with broader audiences. The most pragmatic conversion targets are PDF (3D PDF), STL, OBJ, or standard video formats like MP4 for animations. However, converting these files outside the native software is incredibly difficult. Because the format is closed and proprietary, standard online converters fail to parse the complex 3D geometry and metadata. Often, only the original Dassault Systèmes software can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your SMG file, detects the exact format, and lets you read the text inside.
If you want to convert SMG file to STEP, STP, DWG, DXF, DGN, RVT, RFA, SKP, 3DM, IGES, SAT or X_T, you can use SOLIDWORKS Composer or similar software from the "3D Documentation Assembly File" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART or DXF files to SMG, try SOLIDWORKS Composer or another comparable tool in the "3D Documentation Assembly File" category.
The SMG 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 SMG converter.
