Convert SCH to DWG

Understanding SCH and DWG file formats

SCH files are schematic diagram files commonly used in electronic design automation (EDA) software such as EAGLE or OrCAD. These files store circuit diagrams, including symbols, connections, and component information.

DWG files are a widely used drawing format developed by Autodesk for AutoCAD and other CAD applications. DWG files store 2D and 3D design data, making them a standard for sharing technical drawings in engineering and architecture.

Why convert SCH to DWG?

Converting SCH to DWG allows engineers and designers to share schematic diagrams with professionals who use CAD software, integrate circuit diagrams into larger technical drawings, or prepare schematics for manufacturing and documentation.

How to convert SCH to DWG

Direct conversion from SCH to DWG is not always straightforward, as these formats serve different purposes. However, you can use the following methods:

• Export as DXF, then convert to DWG: Most EDA tools (like EAGLE or OrCAD) allow you to export schematics as DXF files, which can then be opened and saved as DWG in CAD software.
• Use a PDF intermediary: Export the schematic as a PDF, then use a PDF-to-DWG converter. This method may require additional editing for accuracy.

Recommended software for SCH to DWG conversion

• Autodesk EAGLE: Open your schematic, then use File → Export → DXF. Open the DXF in AutoCAD and save as DWG.
• OrCAD Capture: Use File → Export → DXF, then convert the DXF to DWG using AutoCAD or Any DWG DXF Converter.
• Any DWG DXF Converter: A dedicated tool for converting between DXF and DWG formats.
• Online converters: Some online tools can convert DXF to DWG, but always verify the output for accuracy.

Step-by-step example: EAGLE SCH to DWG

1. Open your schematic in EAGLE.
2. Go to File → Export → DXF and save the file.
3. Open the DXF file in AutoCAD.
4. Use File → Save As and select DWG as the format.

Tips for successful conversion

• Check layer mapping and scaling after conversion.
• Review the DWG file for missing symbols or formatting issues.
• Keep backup copies of your original SCH files.
