How to Unfix Parts in SolidWorks?

Understanding Fixed Parts in SolidWorks

In SolidWorks, fixing parts in an assembly is a common practice, as it provides a stable reference for additional components and mates. A fixed part does not move and is essential for maintaining the integrity of your assembly. However, there may come a time when you need to unfix a component to allow for adjustments or reconfigurations.

Steps to Unfix a Part in SolidWorks

  1. Select the Component:
    Open your assembly in SolidWorks. Navigate to the FeatureManager design tree, located on the left side of your screen. Locate the component that you wish to unfix. This part will typically have an (f) preceding its name, indicating that it is fixed.

  2. Open Component Properties:
    Once you have identified the fixed component, right-click on its name in the FeatureManager design tree. This action will bring up a contextual menu filled with options related to that component.

  3. Choose the Unfix Option:
    In the contextual menu, look for the option labeled "Fix," which is currently checked if the part is fixed. Click on this option to uncheck it. This action will effectively unfix the component, allowing it to move freely within the assembly.

  4. Verify the Change:
    After unchecking the "Fix" option, confirm that the component is now mobile by attempting to drag it in the graphics area. The part should move without restrictions, reflecting its new status.

Alternate Methods to Unfix Components

Using the PropertyManager

  1. Access the Move Component Tool:
    Alternatively, you can go to the Assembly toolbar and select the "Move Component" tool. This will open the Move Component PropertyManager.

  2. Select the Fixed Component:
    Click on the fixed part you want to unfix. The cursor should change, indicating that the component is selectable.

  3. Change the Status:
    In the PropertyManager, observe if there’s a checkbox for fixing or unfitting the component. Uncheck this option to unfix.

Confirming the Component’s New Status

After unfixing the part, ensure that the changes have taken effect. You can recheck the FeatureManager design tree; the (f) prefix should no longer be present next to the component’s name. Additionally, as you move the part in the graphics area, it should now be free to adjust.

Troubleshooting Issues

If, after following the steps, the component still appears fixed or does not move:

  • Check for any constraints or mates that might be preventing movement.
  • Analyze if the component is nested within a subassembly, as fixing levels may be impacting its status.
  • Review the assembly settings to ensure that there are no restrictions imposed on the movement of that particular component.

FAQ

1. Can a fixed component be moved again after it has been unfixed?
Yes, once a fixed component is unfixed, it can be freely moved and repositioned as needed within the assembly.

2. What happens to mates when I unfix a component?
When you unfix a component, the existing mates will still apply unless you decide to edit or delete those mates. The part will remain constrained according to the existing relationships.

3. Is there a way to revert a component back to a fixed state after unfixing it?
Absolutely. To fix a part again, right-click on the component in the FeatureManager design tree and select "Fix." The (f) will reappear next to the component name, indicating it is now fixed.
