How Do I Create a Solid Body From Surfaces in SolidWorks?

Creating solid bodies from surfaces is a powerful feature in SolidWorks that allows you to convert complex surface models into fully editable solid models. This capability is especially useful when working with imported or scanned data, where the geometry may be represented by surfaces rather than solids. In this tutorial, we will explore the step-by-step process of creating solid bodies from surfaces in SolidWorks.

Step 1: Importing the Surface Model

Before we begin, make sure you have a surface model imported into your SolidWorks workspace.

To import a surface model, go to File > Open, and select the file containing your surface model. SolidWorks supports various formats such as IGES, STEP, and STL.

Step 2: Preparing the Surface Geometry

Once you have imported the surface model, it’s essential to review and prepare the geometry before creating solid bodies.

  • Clean up any unnecessary or overlapping surfaces: Use the Delete Face tool to remove unwanted surfaces or merge overlapping ones. This step ensures that your final solid body is clean and void of any errors.
  • Create closed volumes: Ensure that all surfaces form closed volumes. If any gaps exist between surfaces, use the Knit Surface tool to close them.

Step 3: Creating Solid Bodies

With your surface model prepared, it’s time to create solid bodies using the Create Solid command.

  1. Select the surfaces: Use the Select Surface tool to choose the surfaces you want to convert into solid bodies. You can either select individual surfaces or use a selection filter for specific types of surfaces.
  2. Define options: Once you have selected the surfaces, you can define various options such as thickness, direction, and offset distance.

    These options allow you to control how the solid bodies are created.

  3. Create solid bodies: Click on the Create Solid button to generate solid bodies from the selected surfaces. SolidWorks will automatically analyze and convert the surfaces into fully editable solid models.

Step 4: Editing and Refining Solid Bodies

After creating the solid bodies, you can further edit and refine them as per your requirements.

To edit a solid body:

  1. Select the desired solid body using the Select Solid Body tool.
  2. Use various editing tools such as extrude, cut, fillet, etc., to modify the shape and features of the solid body.

You can also apply materials, textures, and appearances to enhance the visual representation of your solid bodies.

Tips and Tricks:

  • Delete Surface: If you encounter any issues with a specific surface or want to remove it from a solid body, use the Delete Face tool or delete it directly from within its parent feature.
  • Merging Bodies: If you have multiple solid bodies created from different surface selections but want them to be combined into a single body, use the Combine tool to merge them together.
  • Check for Errors: After creating solid bodies, it’s crucial to run the Check Entity tool to ensure that there are no geometric errors or inconsistencies in your model.

Congratulations! You have now learned how to create solid bodies from surfaces in SolidWorks.

This feature opens up a world of possibilities when working with complex and intricate surface models. With practice and experimentation, you can master this technique and create stunning solid models from even the most challenging surface geometry.
