How Do I Convert SolidWorks to Solid in Surface?

Converting a SolidWorks model to a solid surface is a common task for many designers and engineers. Whether you need to create complex surface models or prepare your design for further analysis, understanding how to convert your SolidWorks model to a solid surface is essential. In this tutorial, we will guide you through the process step by step.

Step 1: Open Your SolidWorks Model

First, open your SolidWorks software and navigate to the file containing the model you want to convert. If you are starting from scratch, create a new model or import an existing one.

Step 2: Convert Your Model

To convert your SolidWorks model into a solid surface, follow these steps:

  1. Select the “Insert” tab.
  2. Click on “Features” in the toolbar.
  3. Select “Surface” from the drop-down menu.
  4. Choose “Thicken” from the options.

This will open the Thicken dialog box, where you can specify the parameters for converting your model to a solid surface.

Step 3: Specify Parameters

In the Thicken dialog box:

  • Specify the thickness: Enter the desired thickness value for your solid surface. This value determines how thick your converted model will be.
  • Select direction: Choose whether you want your solid surface to thicken inward or outward from the original model. This option depends on your specific design requirements.
  • Apply draft: If needed, you can apply draft to your solid surface to facilitate mold creation or improve manufacturability.
  • Click “OK”: Once you have specified all the parameters, click “OK” to convert your SolidWorks model to a solid surface.

After clicking “OK,” SolidWorks will generate a solid surface based on your specified parameters. You can now use this solid surface for further analysis, modeling, or exporting purposes.

Tips and Considerations

Here are a few tips and considerations to keep in mind when converting your SolidWorks model to a solid surface:

  • Simplify complex models: If your model is highly detailed or complex, consider simplifying it before converting it to a solid surface. This can help improve performance and reduce file size.
  • Check for errors: Before converting, make sure your SolidWorks model is free from any errors or inconsistencies.

    Fixing these issues beforehand will prevent any problems during the conversion process.

  • Experiment with different parameters: Depending on your design requirements, you may need to adjust the thickness, direction, or draft of your solid surface. Don’t be afraid to experiment and iterate until you achieve the desired result.


You have successfully converted your SolidWorks model to a solid surface using the Thicken feature. By following these steps and considering the tips provided, you can confidently convert any SolidWorks model into a precise solid surface for further design and analysis purposes.

Remember, practice makes perfect! Keep exploring different features and functionalities in SolidWorks to enhance your design capabilities.
