Can STL File Be Edited in SolidWorks?

STL files are widely used in the 3D printing industry as they contain all the necessary information to create a physical object layer by layer. However, sometimes we may need to make modifications to these STL files using a CAD software like SolidWorks. In this article, we will explore whether it is possible to edit an STL file in SolidWorks and what steps are involved in the process.

Understanding STL Files

STL (Standard Tessellation Language) files are a common file format used for representing 3D models in computer-aided design and 3D printing. They consist of triangular facets that make up the surface of the model. Each facet is defined by three vertices and a normal vector.

The Limitations

By default, SolidWorks does not allow direct editing of STL files like it does with its native file formats such as SLDPRT or SLDASM. This is because an STL file only contains the surface geometry of a 3D model and lacks features that can be edited parametrically.

So, Can We Edit an STL File in SolidWorks?

The answer is yes, but with some limitations. While you cannot directly modify an STL file in SolidWorks, you can convert it into an editable format using SolidWorks’ ScanTo3D feature or by using third-party add-ins available for SolidWorks.

Converting STL to an Editable Format Using ScanTo3D

SolidWorks provides a powerful tool called ScanTo3D that allows you to convert mesh data from scanned objects or imported mesh files into editable solid or surface bodies. Here are the steps:

  1. Open SolidWorks and create a new part or assembly document.
  2. Go to the “Insert” tab and click on the “Mesh” button.
  3. Select the STL file you want to edit and click “Open”.
  4. In the dialog box that appears, choose the appropriate options for units, mesh density, and deviation tolerance.
  5. Click “Next” and select the desired output type (solid or surface).
  6. Click “Finish” to complete the conversion process.
  7. You can now edit the converted model using SolidWorks’ native tools and features.

Using Third-Party Add-ins

If you prefer not to use SolidWorks’ ScanTo3D feature, there are several third-party add-ins available that can help you convert STL files into an editable format. These add-ins provide additional functionality and flexibility when working with STL files in SolidWorks. Some popular add-ins include Rhino3D, MeshLab, and Geomagic Design X.

Closing Thoughts

While SolidWorks does not natively support editing of STL files, it provides tools like ScanTo3D that enable conversion of STL files into editable formats. Additionally, third-party add-ins offer alternative methods for editing STL files within SolidWorks. With these options at your disposal, you can make modifications to your STL files without starting from scratch.

Remember, when working with STL files in SolidWorks or any other CAD software, it’s important to keep in mind that excessive modifications may result in loss of detail or integrity of the original model. Always make backups of your original files before making any changes.
