Convert SLDDRW to 3MF

Understanding slddrw and 3mf file formats

SLDDRW is a drawing file format created by SolidWorks, a popular CAD (Computer-Aided Design) software. These files contain 2D engineering drawings, annotations, and layout information, typically used for manufacturing and documentation purposes.

3MF (3D Manufacturing Format) is a modern file format designed for 3D printing. It stores 3D model data, color, material, and other information in a compact, open-source XML-based structure, making it ideal for additive manufacturing workflows.

How to convert slddrw to 3mf

Direct conversion from SLDDRW (2D drawing) to 3MF (3D model) is not straightforward, as they serve different purposes. However, if your SLDDRW references a 3D model (such as an SLDPRT or SLDASM file), you can export the underlying 3D model to 3MF format using SolidWorks.

Best software for slddrw to 3mf conversion

The recommended software for this conversion is SolidWorks (2017 or newer), as it natively supports exporting to 3MF. Follow these steps:

1. Open your 3D model (SLDPRT or SLDASM) in SolidWorks.
2. Go to File → Save As.
3. In the Save as type dropdown, select 3MF (*.3mf).
4. Click Options to adjust export settings if needed, then click Save.

If you only have the SLDDRW file and not the associated 3D model, you will need to recreate the 3D geometry from the drawing before exporting to 3MF.

Alternative converters

Other CAD software like Autodesk Fusion 360 or FreeCAD can import SolidWorks 3D files and export to 3MF, but they do not support SLDDRW files directly. You must first convert your drawing to a 3D model in SolidWorks or export it as a neutral 3D format (such as STEP or IGES) before using these tools.

Summary

To convert SLDDRW to 3MF, access the original 3D model referenced by the drawing and use SolidWorks to export it as a 3MF file. Direct conversion from a 2D drawing to a 3D printing format is not possible without reconstructing the 3D geometry.
