Mechanical CAD refers to the use of software tools to design, draft, analyze, and document mechanical components, assemblies, and systems. It enables engineers and designers to create detailed 2D drawings and 3D models used in product design, manufacturing, and simulation.

🛠️ Key Uses of Mechanical CAD

• • • 2D Drafting

      • Engineering drawings of parts, machines, and assemblies

      • Includes dimensions, tolerances, material specs

    • 3D Modeling

      • Solid, surface, or sheet metal models

      • Used for visualization, simulation, and prototyping

    • Assembly Design

      • Modeling complex systems by combining multiple parts

      • Includes constraints, motion studies, and interference checks

    • Simulation and Analysis (CAE Integration)

      • Stress, strain, thermal, motion, and flow analysis

      • Often linked with FEA and CFD tools

    • CAM Integration (Computer-Aided Manufacturing)

      • Toolpath generation for CNC machines

      • Used to automate machining processes directly from CAD models

    • Documentation and BOM

      • Automated creation of Bill of Materials (BOM)

      • Technical documentation and exploded views

🧰 Popular Mechanical CAD Software

🔩 Applications of Mechanical CAD
