Summary

The "No Bodies in Part" error indicates that the solid body data within the part file is missing or has become corrupted. When this error occurs, the solid model information was either not successfully saved or has become too damaged for GibbsCAM to recognize.

In most cases, the solid body cannot be recovered. The underlying cause is typically related to a system-level issue rather than the GibbsCAM file itself.

Before You Begin

Before troubleshooting:

  • Determine whether the issue affects a single part file or multiple files.

  • If possible, restore the file from a recent backup or autosave before proceeding.

Note: If the solid body data was not successfully written to the file, there may be no recoverable solid geometry.


Symptoms

You may experience one or more of the following:

  • Opening a part displays the "No Bodies in Part" error.

  • Solid models are missing from the file.

  • Wireframe geometry may still be present while solids are missing.

  • Previously saved solid models cannot be accessed.


Cause

This error indicates that the solid body data could not be read because it was not successfully saved or became corrupted.

Possible causes include:

  • A severely corrupted GibbsCAM installation.

  • Faulty or unstable system memory (RAM).

  • A failing hard drive or solid-state drive.

  • Corruption of Windows system files.

  • Unexpected system shutdowns during file operations.


Procedure

Step 1 - Test Another Part File

  1. Open a different GibbsCAM part.

  2. If other part files open normally, the issue may be isolated to a single damaged file.

Expected Result

Determine whether the problem affects one file or multiple files.

Step 2 - Run the Windows System File Checker

  1. Open Command Prompt as an administrator.

Administrator Command Prompt open at the Windows System32 prompt.

Figure 1 - Administrator Command Prompt

  1. Run the following command:

sfc /scannow

  1. Allow the scan to complete.

  2. If Windows repairs any system files, restart the computer.

Expected Result

Windows verifies and repairs any corrupted operating system files.

Step 3 - Check System Hardware

  1. If the problem continues, perform hardware diagnostics on the workstation.

Recommended tests include:

  • Memory (RAM) diagnostics.

  • Hard drive or SSD health tests.

  • Manufacturer hardware diagnostic utilities.

Expected Result

Any failing hardware components are identified.

Step 4 - Verify the GibbsCAM Installation

  1. If hardware tests pass, perform a complete reinstall of GibbsCAM.

During the reinstall:

  • Remove the User Preferences folder.

  • Uninstall GibbsCAM.

  • Reinstall using the latest installer.

  • Temporarily disable antivirus software during installation if appropriate.

  • Do not migrate previous user preferences until the issue has been resolved.

Expected Result

A clean GibbsCAM installation is created.


Expected Result

Windows system files have been verified, system hardware has been tested, and GibbsCAM has been reinstalled if necessary. If the issue was caused by system corruption or failing hardware, the error should no longer occur on newly created files.


Additional Information

Can the Missing Solid Be Recovered?

Unfortunately, when the "No Bodies in Part" error occurs, the solid body data is typically no longer recoverable. The solid information was either never successfully written to the file or has become too severely corrupted to be recognized.

If backup files or Auto Save files are available, they may contain an earlier version of the model.

Common Issues

This error is most commonly associated with:

  • Corrupted Windows system files.

  • Faulty RAM.

  • Storage device failures.

  • Corrupted GibbsCAM installation files.

  • Unexpected shutdowns while saving.


Best Practices

  • Enable Auto Save and Backup Files whenever possible.

  • Keep Windows fully updated.

  • Regularly monitor storage device health.

  • Run periodic memory diagnostics on engineering workstations.

  • Maintain regular backups of important part files.


Troubleshooting

  • Problem: The error only occurs with one part file.

Possible Causes

  • The file became corrupted during a save operation.

Resolution

Attempt to recover the part from an Auto Save, backup, or previous revision.

  • Problem: Multiple part files display the same error.

Possible Causes

  • Corrupted Windows system files.

  • Hardware failure.

  • Corrupted GibbsCAM installation.

Resolution

Run SFC, perform hardware diagnostics, and reinstall GibbsCAM if necessary.

  • Problem: The issue continues after reinstalling GibbsCAM.

Possible Causes

  • Faulty RAM.

  • Failing storage device.

  • Underlying Windows corruption.

Resolution

Perform comprehensive hardware diagnostics and repair the Windows installation before reinstalling GibbsCAM again.
