Solidworks là một phần mềm thiết kế 3D đa năng với nhiều module hỗ trợ đắc lực cho việc thiết kế tính toán khi thiết kế cơ khí cũng như các lĩnh vực kỹ thuật khác, hiệu quả, dễ sử dụng của hãng Dassault System, đây là phần mềm được kỹ sư và sinh viên các trường đại học khắp thế giới sử dụng vô cùng rộng rãi trong đó có ở Việt Nam. Weldment (Thiết kế khung dầm) và Simulation (Mô phỏng tác động các yếu tố bên ngoài lên chi tiết thiết kế) là hai module rất quan trọng của Solidworks. Sử dụng kết hợp cả hai module giúp người thiết kế thực hiện được rất nhiều dự án.
