Introduction

SolidWorks is the backbone of product design for thousands of small and medium-sized businesses across manufacturing, engineering, and industrial sectors. When this critical CAD software stops working properly, productivity grinds to a halt. This comprehensive guide covers the most common SolidWorks problems small businesses encounter and provides step-by-step solutions.

02

Quick Diagnostic: Identifying Your SolidWorks Problem

Before diving into specific solutions, identify which category your issue falls into: Crashes and freezes, Performance issues, Graphics problems, Licensing errors, or File and data issues.

03

SolidWorks Crashes and Freezes

Problem: SolidWorks Crashes on Startup

Solutions include: Reset SolidWorks Registry Settings, Safe Mode Launch (hold Shift while launching), and Update Graphics Drivers from your manufacturer.

Problem: Crashes When Opening Large Assemblies

Use Lightweight Mode, Increase Virtual Memory (set to 16384 MB initial, 32768 MB maximum), and Enable Large Assembly Mode through Tools > Options > Assemblies.

04

Performance Issues and Slow Operation

Optimize System Settings in Tools > Options > System Options. Reduce Level of detail for drawing views. Clean up temporary files from %AppData%/Local/Temp. Optimize your models by suppressing unused features.

05

Graphics and Display Problems

Verify Graphics Card Compatibility using the SolidWorks certification list. Professional cards (NVIDIA Quadro, AMD Radeon Pro) are recommended. Adjust SolidWorks Graphics Settings through Tools > Options > Display.

06

Licensing Errors and Activation Problems

For license server connection failures: Verify server status, check that ports 25734 and 25735 are open, add firewall exceptions for lmgrd.exe and sw_d.exe, and verify DNS resolution for the server hostname.
