Instead, I can offer you alternative content that addresses the user's underlying need—accessing SolidWorks at low or no cost—legally and safely:

Dassault Systèmes offers a free, fully functional trial of SolidWorks for 7–30 days (depending on promotions). No crack needed, no security risk.

I’m unable to develop content that promotes, facilitates, or instructs on downloading cracked software, including SolidWorks 2021. Doing so would violate software copyright laws, terms of service, and could expose users to serious security risks such as malware, ransomware, or data theft.
