Convert SCAD to DWG

Understanding SCAD and DWG file formats

SCAD files are script-based 3D model files created with OpenSCAD, a popular open-source CAD software. These files contain code that defines 3D objects and their parameters, making them ideal for parametric modeling and design automation.

DWG files are proprietary drawing files used by AutoCAD and other CAD applications. They store 2D and 3D design data, including vector graphics, layouts, and metadata, and are widely used in engineering, architecture, and construction industries.

Why convert SCAD to DWG?

Converting SCAD to DWG allows you to share your parametric 3D models with professionals who use AutoCAD or other DWG-compatible software. This conversion is essential for integrating OpenSCAD designs into broader CAD workflows or for further editing and documentation in industry-standard formats.

How to convert SCAD to DWG

Direct conversion from SCAD to DWG is not natively supported by most software. The typical workflow involves exporting your SCAD model to an intermediary format, such as STL or DXF, and then converting that file to DWG.

1. Open your SCAD file in OpenSCAD.
2. Render your model by clicking Design → Render or pressing F6.
3. Export the model:
   • For 2D designs: Use File → Export → Export as DXF.
   • For 3D designs: Use File → Export → Export as STL.
4. To convert DXF or STL to DWG:
   • Use Autodesk AutoCAD to import the DXF or STL file and then save or export as DWG via File → Save As → DWG.
   • Alternatively, use AnyConv or Zamzar online converters for simple conversions.

Best software for SCAD to DWG conversion

• OpenSCAD: For exporting SCAD to DXF or STL.
• Autodesk AutoCAD: For importing DXF/STL and saving as DWG.
• FreeCAD: Can import STL/DXF and export as DWG with the appropriate add-ons.
• Online converters: Zamzar and AnyConv for quick DXF to DWG conversions.

Summary

While there is no direct SCAD to DWG conversion, exporting your SCAD file to DXF or STL and then converting to DWG using AutoCAD or online tools is the most reliable workflow. This process ensures your parametric designs are accessible in industry-standard CAD environments.
