How to Speed Up SolidWorks Performance Quickly

To speed up SolidWorks performance, optimize your system by increasing RAM, using a certified graphics card, and enabling Lightweight Components. Also, simplify models by suppressing unnecessary features and use Large Assembly Mode for complex projects.

Syntax

SolidWorks performance improvements come from adjusting settings and workflows rather than code syntax. Key actions include:

• Enable Lightweight Components: Loads only essential data for assemblies.
• Use Large Assembly Mode: Optimizes display and rebuild settings for big assemblies.
• Suppress Unused Features: Temporarily disables complex parts to reduce load.
• Adjust System Options: Change settings under Tools > Options for graphics and rebuild.

Enable Lightweight Components: Right-click assembly > Set to Lightweight
Use Large Assembly Mode: Tools > Options > Performance > Enable Large Assembly Mode
Suppress Features: Right-click feature > Suppress
Adjust System Options: Tools > Options > System Options > Performance

Example

This example shows how to enable Lightweight Components and suppress features to speed up assembly loading.

text

1. Open your assembly in SolidWorks.
2. Right-click the assembly name in the FeatureManager design tree.
3. Select 'Set to Lightweight'.
4. Identify complex features or parts you don't need immediately.
5. Right-click those features and select 'Suppress'.
6. Save and reload the assembly to see improved performance.

Output

Assembly loads faster with fewer details initially, improving responsiveness.

Common Pitfalls

Many users try to speed up SolidWorks by upgrading hardware only, ignoring software settings. Others keep all features active, which slows down performance. Using non-certified graphics cards can cause display lag or crashes.

Also, large assemblies without using Lightweight or Large Assembly Mode cause slow rebuilds and lag.

Wrong way:
- Keep all features active
- Use default graphics settings

Right way:
- Suppress unused features
- Enable Lightweight Components
- Use certified graphics card
- Adjust performance options

Quick Reference
