4. How Designers Life Before CAD Looks Like (1750-1980’s) Before the advent of CAD software, the engineering drawings were made on the sheet of papers using drawing boards. Almost 20 years ago, engineers and toolmakers used to draw all things on paper with the help of drafting tools and pencils. Many types of equipment were required to complete a given drawing. The major disadvantage of the paper-based design was that you can not actually change it after it’s been put on paper AutoCAD is a 2D and 3D computer-aided design (CAD) software application for desktop, web, and mobile developed by Autodesk. It was first released in December 1982.

5. CAD (Computer-Aided Design) Introduction CAD (computer-aided design) is the use of computer-based software to aid in design processes. CAD software is frequently used by different types of engineers and designers. CAD software can be used to create two-dimensional (2-D) drawings or three-dimensional (3-D) models. The purpose of CAD is to Optimize and streamline the designer's workflow, Increase productivity, Improve the quality and level of detail in the design, Improve documentation communications and often contribute toward a manufacturing design database. CAD software allows users to Conceptualize ideas, Produce designs and drawings to the required levels of technical accuracy, And even perform rapid design calculations and simulations; across a wide range of industries.

6. Native CAD file formats are designed to be usable only on that specific proprietary CAD software. Neutral CAD file formats are interoperable between different CAD software, allowing data to be imported and exported by different applications.

7. Real-Time Use Cases Automotive industry: Suspension, engine parts Aerospace: Structural components Consumer goods: Product design & ergonomics Robotics: Linkages & actuators

8. 1. Introduction to CAD Tools Explored the layout, navigation tools, and essential features of the SolidWorks environment . Learned to create basic 3D parts by practicing sketching techniques and applying key operations such as extrusion and revolving. Technical drawing standards were also introduced, focusing on orthographic projections and standard views. Key Features: Part Assembly Drawing

9. Introduction to SolidWorks Solidworks is a solid modeling Computer-Aided Design (CAD) and computer aided engineering (CAE) application . Developed by Dassault Systems. Solidworks corporation was founded in December 1993 . Initial rleased on November 1,1995. In 1997 Dassault Systems best known for its CATIA CAD software. Stable release- SolidWorks 2023

17. 2. Quick Return Mechanism A Quick Return Mechanism is a type of reciprocating mechanism in which the return stroke takes less time than the forward stroke. This is beneficial in machining operations where material is removed during the forward stroke, while the return stroke is idle Explored the Quick Return Mechanism (QRM), a fundamental mechanical system widely used in shaping and slotting machines . Modeling key components of the mechanism using SolidWorks . These parts included the crank, slotted link, and ram Subsequently, all modeled components were assembled using mates Finally, the assembled mechanism underwent motion testing using animation and basic motion study tools.

18. 3. Belt Roller System Focused on the design, modeling, and documentation of a Belt Roller System, a widely used mechanical assembly in conveyor and material handling systems . E ngaged in individual part modeling of each element in SolidWorks . These parts were brought together through the assembly module using various mates and constraints to simulate realistic mechanical movement and spatial alignment . Guided through the process of creating detailed 2D engineering drawings, including dimensioning, annotation, and tolerance application Concluded with the creation of exploded views and a comprehensive Bill of Materials (BOM).

19. 4. Sheet Metal Basics Began with an overview of the sheet metal design environment in SolidWorks , including key tools such as Base Flange, Edge Flange, Hem, Jog, and Reliefs . Guided through creating basic sheet metal parts, understanding the design constraints involved, and exploring how these parts are manufactured in real-world applications . Engaged in creating flat patterns and understanding bend allowances, K-factors, and bend deductions . U ndertook a mini-project involving the design of a practical sheet metal part, such as a mounting bracket or enclosure box . F ocused on exporting flat patterns to DXF formats for laser cutting and documenting the design with proper drawings, annotations, and BOM.

20. 5. Motion Simulation Tools Introduced to the SolidWorks Motion Study interface and explored the differences between simple animations and analytical motion simulations . Gained familiarity with motion manager, time bars, and simulation types. Practiced setting up mechanical mates such as concentric, coincident, and gear mates . Modeled a slider-crank mechanism , integrating multiple parts and observing the dynamic interaction among them

21. 6. Advanced Surface Modeling Hands-on practice with key features such as Loft, Sweep, and Boundary surfaces. Participants L earned how to control tangency and curvature continuity between profiles to ensure smooth transitions, which is essential for creating aerodynamic and ergonomic designs Introduced to surface editing tools, including Trim, Extend, Knit, and Thicken, to combine multiple surfaces into closed volumes ready for manufacturing . Added details, performed rendering, and created exploded views and documentation. This included applying materials, realistic visualizations, and preparing technical drawings for production or presentation.

22. Internship outcomes Proficiency in SolidWorks Modules Hands On Experience in Part and Surface Modeling Exposure to design for manufacturing Confidence to work on Industrial design tools
