Convert SLDASM to IDF

Understanding sldasm and idf file formats

SLDASM is the file extension for SolidWorks Assembly files, which store 3D assembly data, including references to individual part files and their spatial relationships. IDF (Intermediate Data Format) is a standard file format used for exchanging PCB (Printed Circuit Board) design data between ECAD (Electronic Computer-Aided Design) and MCAD (Mechanical Computer-Aided Design) systems. IDF files typically come in pairs: .emn (mechanical) and .emp (electrical) files.

Why convert sldasm to idf?

Converting SLDASM to IDF is essential for integrating mechanical assembly designs with PCB layouts, enabling collaboration between mechanical and electrical engineering teams. This conversion streamlines the process of ensuring that PCB designs fit correctly within mechanical enclosures.

How to convert sldasm to idf

Direct conversion from SLDASM to IDF is not natively supported in most CAD software. The typical workflow involves exporting the assembly from SolidWorks to a format compatible with IDF export, such as a PCB assembly or using a plugin.

1. Open your assembly in SolidWorks.
2. Install the SolidWorks CircuitWorks add-in, which provides IDF import/export capabilities.
3. Enable CircuitWorks via Tools → Add-Ins → CircuitWorks.
4. With CircuitWorks active, go to File → Export → CircuitWorks or File → Save As and select IDF (*.emn, *.emp) as the file type.
5. Follow the prompts to configure the export settings and save your IDF files.

Best software for sldasm to idf conversion

• SolidWorks with CircuitWorks add-in: The most reliable and accurate method for converting SLDASM to IDF, as it is designed for ECAD-MCAD collaboration.
• Altium Designer: Can import mechanical data from SolidWorks and export to IDF, but may require intermediate steps.
• Autodesk Fusion 360: Supports IDF import/export and can work with SolidWorks files via intermediate formats.

Tips for successful conversion

• Ensure all referenced part files (.sldprt) are available and properly linked in your SLDASM assembly.
• Check the exported IDF files in your ECAD software to verify correct component placement and board outline.
• Use the latest versions of both SolidWorks and CircuitWorks for best compatibility.
