SOLIDWORKS 2025 delivered notable updates, but some users encounter recurring stability and data integrity issues that can be resolved with targeted workflows and timely updates. For reliability, always validate your graphics drivers, add-ins, and service packs before deep troubleshooting, and keep backups of projects and simulation studies.
Lost mates after rebuild
Intermittent loss of mates after rebuild typically arises from renamed faces, suppressed components, flexible subassemblies, or rebuild order changes in complex assemblies in 2025. It often correlates with large assembly workflows and graphics pipeline behavior, so verifying assembly performance settings helps prevent repeat breakage.
Step-by-step fix
- Run Force Rebuild (Ctrl+Q) on the top assembly, then evaluate MateXpert for failed mates and suppressed components.
- Switch subassemblies from Flexible to Rigid where possible to stabilize mate solving, then rebuild again.
- Use Large Assembly Mode and Lightweight components to minimize graphics and memory churn during rebuilds.
- Reattach mates using stable references such as planes, axes, or reference geometry instead of transient faces.
- Update to the latest 2025 service pack to inherit mate-solving and performance fixes.
Low memory warnings
Users upgrading to 2025 frequently see low memory warnings on big assemblies or drawings, especially on systems with inadequate RAM, pagefile settings, or outdated GPU drivers. Optimizing hardware prerequisites, virtual memory, and large assembly settings typically eliminates these warnings.
Step-by-step fix
- Increase Windows virtual memory (pagefile) to at least system RAM size and restart SOLIDWORKS.
- Enable Large Assembly Mode and set components to Lightweight or Large Design Review as needed.
- Close unused documents and purge hidden bodies to free memory during long sessions.
- Update certified graphics drivers and disable background add-ins to reduce memory footprint.
- Move to the newest 2025 SP to benefit from memory and stability improvements.
PDM check-in problems
Check-in failures in 2025 are often caused by cached file mismatches, reference path conflicts, permissions, or add-in state inconsistencies in the vault view. Aligning local cache and references, plus confirming correct vault login and add-in status, resolves most user-side cases.
Step-by-step fix
- Log into the correct vault and verify permissions for the target folder and workflow state.
- Clear Local Cache for the affected folder and run Get Latest to align references.
- In SOLIDWORKS, enable the PDM add-in and resolve missing or ambiguous file references before check-in.
- Rename any locally edited but not versioned files that clash with vault items and retry.
- If issues persist, update to the latest PDM 2025 client/server SP and review Technical Alerts.
Splash-screen crash
Some 2025 installations hang at the splash screen or crash early, frequently linked to problematic add-ins, corrupted settings, or specific modules like Marketplace. Launching in safe mode to isolate add-ins is the fastest path to a stable startup.
Step-by-step fix
- Launch SOLIDWORKS Rx in safe mode (bypass add-ins) and confirm the program starts cleanly.
- Disable nonessential add-ins on normal launch, prioritizing isolation of Marketplace and third-party extensions.
- Reset SOLIDWORKS registry settings to defaults using Rx if crashes persist after disabling add-ins.
- Update or repair installation, then apply the latest 2025 service pack for startup fixes.
- Keep GPU drivers current and test with Enhanced Graphics Performance toggled off.
Simulation study corruption
A known 2025 Simulation issue can cause study corruption or “Storage for study [name] is not found,” especially when switching between files in SP1.2–SP2. Dassault/VARs provided a targeted hotfix and guidance to prevent recurrence.
Step-by-step fix
- Install the official Simulation 2025 hotfix addressing study corruption and missing storage errors.
- Avoid switching documents during solves and finish meshing/solving before navigating away.
- Save studies under new names after repair and verify results integrity before proceeding.
- Update to the latest 2025 SP beyond SP2 if available to roll in permanent fixes.
- Maintain regular backups of .SLDPRT/.SLDASM and study files to reduce recovery effort.
BOM not updating in SP2
Users reported that BOM and configuration tables may not refresh reliably in SOLIDWORKS 2025 SP2.0 until forcing updates or applying refresh fixes. Ensuring rebuilds propagate and tables are re-evaluated typically restores correct display.
Step-by-step fix
- Use Force Rebuild (Ctrl+Q) on the assembly and drawing, then right‑click BOM and choose Update Table.
- Toggle configuration-specific properties and reselect configurations to force a BOM refresh.
- Delete and reinsert the BOM if it remains stale, then save and reopen to confirm.
- Apply any refresh-related hotfixes and update to the newest 2025 SP.
- If PDM is involved, run Get Latest on referenced parts before regenerating the BOM.
Crash when editing with transparent tree
Some users observe crashes while editing features (e.g., extrude depth) when UI transparency or graphics acceleration interacts poorly with 2025 on specific drivers. Disabling the transparency feature and adjusting graphics settings stabilize editing sessions.
Step-by-step fix
- Turn off transparent flyout/FeatureManager UI options in System Options to remove the transparency overlay.
- Disable Enhanced Graphics Performance and restart to test a stable editing pipeline.
- Update to certified GPU drivers and re-enable features one by one to isolate the trigger.
- Apply relevant general hotfixes for 2025 addressing UI and graphics crashes.
- Move to the latest 2025 SP to capture cumulative stability fixes.

Conclusion
Keeping SOLIDWORKS 2025 patched, minimizing risky add-ins, and using Rx safe mode to isolate issues will resolve most startup, stability, and data integrity problems quickly. For known defects like Simulation study corruption and SP2 table refresh issues, apply the official hotfixes and monitor Technical Alerts to stay ahead of regressions.
