Engineers used CAD software to craft three-dimensional representations of the product or structure, necessitating profound comprehension of engineering, geometry, and spatial relationships. With careful attention to detail, engineers design the components to ensure precision and accuracy. 3D modelling minimises design errors like clashes and tolerance issues, facilitating necessary adjustments before advancing further.

Step 4: Analysis and Simulation

After the 3D model is created, engineers conduct comprehensive simulations to assess the performance and feasibility of a part or assembly. Advanced CAD software allows for such simulations as stress analysis, fluid dynamics, thermal analysis and cyclic/dynamic loading. Engineers can then evaluate the data provided and identify potential weaknesses or areas that require improvement. 

Step 5: Iteration and Refinement

The CAD and design process is inherently iterative. Engineers evaluate simulation data to refine the design, making necessary iterations to address the shortcomings. Continuous improvement is paramount, with engineers collaborating closely to discuss potential solutions and enhancements. This iterative process persists until the design achieves an optimal state, prepared for creating the 2D technical drawings and manufacturing data.

Step 6: 2D Drafting & Manufacturing Data

Once the design undergoes analysis and the 3D models are checked and approved, our engineers develop detailed 2D technical drawings, manufacturing data, and production schedules. These technical drawings include essential dimensions, tolerances, and annotations to convey the design intent to the manufacturing and production teams. The information outlined in the 2D technical drawings, schedules, bills of materials (BOM), and assembly instructions serves as the foundation for the successful manufacturing of the product.
