Understanding sldasm and dgn file formats
SLDASM is the file extension for SolidWorks Assembly files, which are used to store 3D assembly data in the SolidWorks CAD software. These files contain references to multiple part files (SLDPRT) and define how these parts fit together in a 3D space.
DGN is a file format used by Bentley Systems' MicroStation and other CAD software. It is commonly used in civil engineering, construction, and infrastructure projects for storing 2D/3D design data.
Why convert sldasm to dgn?
Converting SLDASM to DGN is often necessary when collaborating between teams using SolidWorks and MicroStation, or when integrating mechanical designs into larger infrastructure projects.
How to convert sldasm to dgn
Direct conversion from SLDASM to DGN is not natively supported in most CAD software. The typical workflow involves exporting the assembly to an intermediary format such as STEP (.step, .stp) or IGES (.igs, .iges), which can then be imported into MicroStation and saved as a DGN file.
Step-by-step conversion process
- Open your assembly in SolidWorks.
- Go to File → Save As and select STEP (*.step, *.stp) or IGES (*.igs, *.iges) as the file type.
- Save the exported file to your computer.
- Open MicroStation or Bentley View.
- Use File → Import to bring in the STEP or IGES file.
- Once imported, go to File → Save As and choose DGN as the output format.
Best software for sldasm to dgn conversion
- SolidWorks – for exporting assemblies to STEP or IGES.
- MicroStation – for importing intermediary files and saving as DGN.
- Bentley View – a free viewer from Bentley that can import and save DGN files.
There are also online converters and third-party tools, but for best results and to preserve assembly structure, using the native software is recommended.
Tips for successful conversion
- Ensure all referenced part files are available when exporting from SolidWorks.
- Check the imported geometry in MicroStation for accuracy and completeness.
- Consider simplifying the assembly if only certain components are needed in the DGN file.
