Topology optimization has emerged as a transformative computational technique in engineering design, enabling the development of lightweight, high-performance structures through systematic material distribution optimization. This review paper examines the fundamental principles of topology optimization, focusing on the integration of Computer-Aided Design (CAD) and Finite Element Analysis (FEA) tools in modern engineering workflows. The study provides a comprehensive overview of topology optimization methodologies, particularly the Solid Isotropic Material with Penalization (SIMP) method, and explores their applications across automotive, aerospace, and mechanical engineering domains. Special emphasis is placed on the capabilities of industry-standard software packages, namely ANSYS for structural analysis and optimization, and CATIA for parametric modeling and design refinement. The paper presents a detailed methodology for implementing topology optimization workflows, including step-by-step procedures for CAD model preparation, FEA setup in ANSYS, and post-optimization design refinement. A comprehensive literature review synthesizes recent advances in lightweight design, additive manufacturing integration, and multi-objective optimization strategies. The synthesis of current research trends reveals significant opportunities for weight reduction in mechanical components while maintaining structural integrity, with implications for sustainability and performance enhancement in various engineering applications. This work serves as a foundational resource for researchers and practitioners seeking to understand and implement topology optimization techniques in structural design without compromising strength.
