Convert SLDASM to PLY

Understanding sldasm and ply file formats

SLDASM is the file extension for SolidWorks Assembly files, which are used to store 3D assembly data in the SolidWorks CAD software. These files contain references to multiple part files (SLDPRT) and define how these parts fit together in a 3D space.

PLY (Polygon File Format or Stanford Triangle Format) is a file format widely used for storing 3D model data, especially in the context of 3D scanning and printing. PLY files can store both geometry (vertices, faces) and properties such as color and transparency.

Why convert sldasm to ply?

Converting SLDASM to PLY is useful when you need to use your SolidWorks assemblies in 3D applications that support PLY, such as 3D scanning, mesh processing, or visualization tools. PLY is a common format for 3D printing and mesh-based workflows, while SLDASM is proprietary to SolidWorks.

How to convert sldasm to ply

Direct conversion from SLDASM to PLY is not natively supported in most software, as SLDASM is a proprietary format. The typical workflow involves exporting the assembly to an intermediary mesh format (like STL or OBJ) and then converting that to PLY.

Step-by-step conversion using SolidWorks and MeshLab

1. Open your assembly in SolidWorks.
2. Go to File → Save As and select STL (*.stl) or OBJ (*.obj) as the file type. Save the file.
3. Download and install MeshLab (free and open-source).
4. Open MeshLab and go to File → Import Mesh to load your STL or OBJ file.
5. Once loaded, go to File → Export Mesh As and select PLY (*.ply) as the output format.
6. Adjust export settings if needed and save your PLY file.

Recommended software for sldasm to ply conversion

• SolidWorks – for exporting SLDASM to STL or OBJ.
• MeshLab – for converting STL/OBJ to PLY and further mesh processing.
• FreeCAD – can also import STL/OBJ and export to PLY.

Tips and considerations

• Ensure all referenced part files are available when opening SLDASM in SolidWorks.
• Check mesh quality and resolution during export to avoid loss of detail.
• PLY supports color and other properties; ensure your intermediary format preserves necessary data.
