Assembly Performance Improvements

Assembly performance is improved when:

  • Searching with Include sub-folders selected.

    To select this option, click Tools > Options > External References > Reference Documents specified in File Locations > Include sub-folders.

  • For assemblies that contain parts with multiple imported bodies and body level appearances:
    • Opening a file
    • Changing a configuration
    • Applying, modifying, or removing an appearance
    • Rolling back or rolling forward assembly items
  • Saving assemblies is faster as only changed model data is saved. This improvement is noticeable in very large assemblies. Previously, SOLIDWORKS saved all model data when an assembly or a component changed.
