Can you mirror a component to the other side of an assembly in SolidWorks?
Short Answer
Yes, you can mirror a component to the other side of an assembly in SolidWorks using the Mirror Components command, which is the most common professional method for creating opposite-hand parts or symmetric assembly layouts. This works best when a clear mirror plane exists. It may fail if mates, handed geometry, or file-link behavior are not handled correctly.
What You Need to Know Before
Warning: Mirroring a component in SolidWorks can create either a reused opposite instance or a new opposite-hand part, and choosing the wrong option can break downstream drawings, bom structure, or manufacturing references. A very common failure is mirrored components losing expected mate alignment when the selected mirror plane does not match the assembly design intent.
How to Mirror a Component to the Other Side of an Assembly in SolidWorks
Command: Mirror Components
Shortcut: No default keyboard shortcut
Quick Steps:
- In the assembly, go to the Assembly tab on the CommandManager and click Mirror Components.
- Select a plane or planar face as the Mirror Face/Plane, then select the component(s) to mirror in Components to Mirror.
- Choose the needed option such as Reuse components or create opposite-hand versions, review mate results, then click OK.
Variables & Settings
Key Setting: Reuse components
Expert Setting: This option controls whether SolidWorks places a mirrored instance of the same part or creates a new mirrored part file. In professional workflows, use Reuse components for symmetric hardware or non-handed parts, and create a new opposite-hand file only when geometry must truly exist as left-hand/right-hand production parts.
Why it Fails
Cause 1 (Geometry): The selected mirror plane is incorrect or not centered on the design intent, so the mirrored component lands in the wrong location or orientation.
Cause 2 (layers/Locks): The target component files may be read-only, managed by PDM, or not writable, which can block creation of new opposite-hand files.
Cause 3 (Command/Logic): The wrong mirror option is chosen—reusing a component when a handed part is required, or creating a new file when only a mirrored placement was needed.
Quick Fix & Best Practice
Quick Fix: Edit the feature and switch the mirror definition to the correct Mirror Face/Plane, then verify the Reuse components option before accepting the feature.
Manager’s Verdict: Use Mirror Components for standard symmetric assembly work because it is fast, clean, and easy to manage. Avoid creating opposite-hand files unless manufacturing, BOM tracking, or tooling actually requires unique left/right parts.
FAQ
Can mirrored components keep mates in SolidWorks?
Yes, but mate results depend on the mirror plane and component geometry.
Can you mirror only the position without creating a new part?
Yes, use Reuse components to place a mirrored instance of the same component.
Can you create left-hand and right-hand parts from mirroring?
Yes, SolidWorks can create new opposite-hand part files during the mirror process.
