Introduction

In SolidWorks, managing complex assemblies often involves working with multiple bodies and parts. When designing, engineers frequently need to isolate, modify, or export individual solid bodies as separate parts. Learning how to save solid bodies as separate parts in SolidWorks is an essential skill to streamline workflows, facilitate detailed editing, and prepare parts for manufacturing or collaboration.

This process, though straightforward for experienced users, can be confusing for beginners. In this comprehensive guide, we’ll walk through step-by-step instructions, practical examples, common mistakes to avoid, and best practices to efficiently save solid bodies as individual parts within SolidWorks.

Understanding Solid Bodies and Parts in SolidWorks

Before diving into the process, it’s crucial to understand the difference between solid bodies and parts within SolidWorks:

• Solid Bodies: These are the individual 3D shapes within a part file. A single part can contain multiple bodies.
• Parts: These are individual files in SolidWorks representing a single component or object, typically created from a solitary solid body or an assembly.

Why Save Solid Bodies as Separate Parts?

• To prepare components for manufacturing
• To facilitate detailed editing
• To simplify complex assemblies
• To make component sharing easier

Now, let’s explore clear, actionable steps to save solid bodies as separate parts.

How to Save Solid Bodies as Separate Parts in SolidWorks

The process generally involves isolating each solid body and exporting it as a new part file. This allows precise control over individual components.

1. Open the SolidWorks file containing multiple solid bodies

• Load your complex part or assembly containing multiple solid bodies.
• Confirm all bodies are visible in the FeatureManager Design Tree.

2. Use the “Move/Copy Bodies” feature to organize bodies

• Go to the `Insert` menu.
• Select `Features` > `Move/Copy Bodies`.
• The Move/Copy Bodies dialog appears.

Practical tip:

• If you don’t see the bodies listed, ensure they are not hidden or suppressed.

3. Select the bodies to save as separate parts

• In the Move/Copy Bodies dialog, select the bodies you wish to export.
• You can isolate each body one by one for individual export.

4. Save each body as a separate part

This process involves converting each solid body into a separate part file. You have two main options:

Option A: Use “Save Bodies” feature (recommended for multiple bodies)

This is the most efficient way to save multiple solid bodies as individual parts without re-creating them.

• With your solid body or bodies selected, go to `Insert` > `Features` > `Save Bodies`.
• The Save Bodies property manager appears.
• Select the bodies you want to save.
• Choose a destination folder.
• Name each body (optionally, you can specify file names).

Click `OK`. SolidWorks creates separate part files for each selected body.

Option B: Export each body manually

If you prefer manual control or are working with very few bodies:

• Isolate a single solid body.
• Use `File` > `Save As`.
• Choose “Part (*.sldprt)” as the file type.
• Save the body as a new file.
• Repeat for each body.

5. Verify the saved parts

• Open each newly created part file to ensure that it contains only the intended solid body.
• Check for any missing features or errors.

Best Practices and Pro Tips for Saving Solid Bodies

• Use “Save Bodies” for multiple solid bodies; it’s faster and minimizes manual errors.
• Name files descriptively to keep track of each part easily.
• Suppress unwanted bodies before saving to avoid clutter.
• Create backup copies before making significant modifications.
• Consistently organize saved parts in dedicated project folders.

Common Mistakes to Avoid

• Not selecting the correct bodies before saving — double-check the selection.
• Forgetting to update references if the bodies are linked to other features.
• Saving with generic file names that make identifying parts difficult.
• Not verifying the exported parts to ensure the integrity of each solid body.
• Overlooking the importance of proper units/formats, which can cause misfits during manufacturing.

Practical Example: Saving Multiple Bodies in a Gearbox Housing

Suppose you designed a gearbox housing with multiple internal and external features as separate solid bodies.

Workflow:

1. Use `Save Bodies` to select all the internal partitions and external shells.
2. Save each as a separate part with clear naming conventions like `HousingMain.sldprt`, `InternalBracket.sldprt`.
3. Verify each exported part aligns with intended design specifications.
4. Use these parts for detailed manufacturing drawings or 3D printing.

Comparison: Saving Solid Bodies vs. Exporting as Mesh or Drawing

Tip: Always choose the method best suited for your project phase—design, manufacturing, or visualization.

Conclusion

Saving solid bodies as separate parts in SolidWorks is a vital technique for efficient design management and manufacturing preparation. By following structured steps—using features like Save Bodies, manually saving, and organizing files—you can streamline your workflow and avoid common pitfalls.

Mastering this skill enhances your ability to work with complex models, deliver accurate parts, and collaborate effectively with manufacturing teams. Incorporate these best practices into your SolidWorks routine to maximize productivity and precision.

FAQ

1. How do I save multiple solid bodies as separate parts in SolidWorks?

Ans: Use the “Save Bodies” feature from the Insert > Features menu to convert selected solid bodies into individual part files automatically.

2. Can I export solid bodies as STL files instead of separate parts?

Ans: Yes, but STL files are mesh-based and not editable; they are mainly used for 3D printing or visualization, not for further CAD editing.

3. Is there a way to automate saving solid bodies as parts?

Ans: Yes, you can create macros or use third-party tools to automate the process, especially for complex models with many bodies.

4. How do I ensure that the saved parts contain only the intended solid body?

Ans: Double-check the selection in the Save Bodies dialog and verify each exported part by opening it in SolidWorks.

5. What should I do if the saved parts are missing features?

Ans: Make sure the original solid bodies are fully defined and not suppressed or hidden during the saving process.

6. Can I link the original bodies and exported parts for updates?

Ans: Generally, saved part files are independent; updates require re-exporting or using configurations to maintain links.

7. What are common mistakes when saving solid bodies as parts?

Ans: Common mistakes include selecting incorrect bodies, not verifying the exported parts, and using inconsistent naming conventions.
