Can SolidWorks OpenSCAD Files?

OpenSCAD is a powerful open-source software tool used for creating 3D models. It uses a scripting language to define geometric shapes and combine them to create complex objects. On the other hand, SolidWorks is a popular computer-aided design (CAD) software widely used in industries for designing and engineering purposes.

One common question that arises is whether SolidWorks can open OpenSCAD files. The short answer is no, but there are workarounds that can be employed to bridge the gap between these two software tools.

The Limitations of SolidWorks

SolidWorks primarily works with parametric modeling, where the design intent is captured using features and dimensions. This approach allows for easy modification of designs and provides powerful tools for creating intricate models.

However, OpenSCAD takes a different approach by using constructive solid geometry (CSG) techniques to build models. Instead of manipulating parameters, OpenSCAD focuses on defining shapes using operations such as union, difference, and intersection.

Converting OpenSCAD Files for SolidWorks

If you have an OpenSCAD file that you want to use in SolidWorks, you’ll need to convert it into a format that SolidWorks can recognize. This can be done by exporting the file from OpenSCAD into a common 3D file format like STL (Standard Tessellation Language) or STEP (Standard for the Exchange of Product Data).

To export an OpenSCAD file as an STL file, you can use the write() function in your script:

write("model.stl", model);

This will save your model as an STL file that can be imported into SolidWorks.

Alternatively, you can also use the OpenSCAD software itself to export the model as an STL file. Simply go to the File menu, select Export, and choose STL as the file format.

Once you have the STL file, you can import it into SolidWorks using the “Insert” menu. From there, you can perform any necessary modifications or further design work on the model.

Considerations for Conversion

It’s important to note that when converting an OpenSCAD file to SolidWorks, certain limitations may apply:

  • The resulting SolidWorks model may not retain all of the original OpenSCAD features or operations used in its creation.
  • The complexity of the OpenSCAD model may affect its compatibility with SolidWorks. Highly intricate models with numerous operations may not convert accurately.

Therefore, it’s advisable to review and validate the converted model in SolidWorks before proceeding with any critical design work or manufacturing processes.


While SolidWorks cannot directly open OpenSCAD files due to their differing modeling approaches, it is still possible to use OpenSCAD models within SolidWorks by converting them into compatible formats like STL or STEP. This allows for collaboration between users of both software tools and enables further design modifications and enhancements using SolidWorks’ powerful features. However, it’s essential to consider any limitations or loss of information during the conversion process.

In summary, while there is no direct compatibility between SolidWorks and OpenSCAD files, with proper conversion techniques in place, you can leverage both tools effectively in your design workflow.
