Convert IGS to SLD

Understanding IGES and SLD file formats

IGES (Initial Graphics Exchange Specification, .igs or .iges) is a widely used neutral file format for exchanging 2D and 3D CAD data between different CAD systems. It is especially popular for sharing wireframe, surface, and solid models in engineering and manufacturing industries.

SLD files are typically associated with SolidWorks, a leading CAD software. The SLD file extension can refer to several SolidWorks file types, such as SLDPRT (part), SLDASM (assembly), or SLDDRW (drawing). These are proprietary formats that store parametric 3D models, assemblies, or 2D drawings.

How to convert IGES to SLD

Converting an IGES file to a SLD file (such as SLDPRT or SLDASM) typically involves importing the IGES file into SolidWorks and saving it in the desired SLD format. This process allows you to work with the geometry natively in SolidWorks, enabling further editing and parametric modeling.

Step-by-step conversion using SolidWorks

1. Open SolidWorks.
2. Go to File → Open and select your .igs or .iges file.
3. SolidWorks will import the IGES file. You may be prompted to select import options (such as importing as a solid body or surface body).
4. Once the file is open, review and repair any geometry issues if necessary.
5. To save as a SolidWorks part, go to File → Save As and choose SLDPRT as the file type.
6. For assemblies, save as SLDASM if the IGES file contains multiple parts.

Recommended software for IGES to SLD conversion

• SolidWorks – The most reliable and accurate way to convert IGES to SLDPRT or SLDASM files.
• Autodesk Inventor – Can import IGES and export to SolidWorks formats, but may require additional steps.
• FreeCAD – Open-source alternative that can import IGES and export to STEP, which can then be opened in SolidWorks.

For best results and full feature compatibility, SolidWorks is the recommended software for this conversion.

Tips for successful conversion

• Check the imported geometry for errors or missing features.
• Use SolidWorks' Import Diagnostics tool to repair surfaces or solids if needed.
• Save a backup of the original IGES file before conversion.
