When working with large assemblies in CAD, performance degradation is common. A key strategy is to use lightweight components for parts that don't need full detail during assembly editing. This reduces memory usage and speeds up rotations and zooms. You can set default behavior to open large assemblies in lightweight mode.

Another effective technique is to simplify complex mates. For example, avoid using concentric and coincident mates on every bolt and washer. Instead, create subassemblies of fasteners and use pattern features or simplified mate groups. This drastically reduces the solver's workload.

Additionally, suppress or hide unnecessary features like fillets, threads, or cosmetic details when working at the top assembly level. Use configuration-specific supression to keep those details for drawings. Also consider using speedpak or large assembly mode tools if available in your software.

Finally, organize your assembly tree logically. Group similar parts into folders and use subassemblies to break down the structure. This not only improves performance but also makes navigation easier. Implement these tips to maintain smooth workflow even with thousands of components.
