1. Computer Aided Design
What is CAD?
Computer-Aided Design (CAD) refers to the use of computer software to create, modify, analyze, and optimize designs. CAD is widely used in engineering, architecture, manufacturing, and product design.
It allows designers to create both 2D drawings and 3D models with precision and efficiency. It allows developers to manage code versions, work on branches, and merge changes seamlessly.
Key features of Git include:
2D – Used for creating technical drawings, schematics, and plans.
3D – Used for designing three-dimensional objects and assemblies.
Parametric CAD – Uses constraints and relationships between elements to control design modifications.
Modeling – Allows flexible modifications without predefined constraints.
For the final project
3D modeling for mechanical design.
Simulation & analysis to test structural integrity.
Rendering & animation to visualize the tray’s movement.
3D printing for prototyping and and circuit box.
- Learning outcome for CAD Modeling
- CorelDraw design
- SolidWorks designs
- Fusion Designs
-
Raster and Vector Graphics
a. Differentiate between raster (pixel-based) and vector graphics. -
2D Modeling
a. Create technical drawings using lines, arcs, and geometric constraints. -
3D Modeling
a. Design solid and surface models using parametric and direct modeling techniques. -
Rendering
a. Apply materials, textures, and lighting to enhance visual realism. -
Animation
a. Create exploded view animations to showcase assembly and disassembly. -
Simulation
a. Perform structural stress analysis to evaluate design strength.
b. Utilize vector-based tools for precise CAD designs and technical drawings.
c. Optimize raster images for reference in CAD modeling.
b. Develop dimensioned sketches for further 3D modeling.
c. Convert hand-drawn sketches into digital 2D representations.
b. Construct assemblies by combining multiple 3D components.
c. Apply constraints and joints to ensure proper movement of mechanical parts.
b. Generate high-quality renders for product visualization and presentations.
c. Export rendered images in different formats for documentation.
b. Simulate motion paths to visualize how the design moves in real life.
c. Produce short animation clips for demonstrations.
b. Simulate kinematics and motion to analyze moving parts.
The design for both projects are as follows
Food delivery tray
Free energy generator
Firstly I opend Corel Draw software to start design.
I used rectangle tool to create tray, frame, shelf and the eclips to create wheels.
I used eclips tool to create wheels and the virtual segment delete tool, and combined in one object.
I used extrude tool to covert to 3D dsign.
Coloring the model
I selected each object to give it a colour. The recent colours used appears at the bottom of the workspace. It is found under emboss tool.
Converted object into bitmap top roduce raster image.
Used different styles to apply on bitmap image like plastic, stone, planes
This is the final product.

Food Delivery Tray
Free energy generator
These outcomes will assist in model, visualize, and test of remote-controlled food delivery tray in CAD software.
To design my model I used Corel Draw, this is becase I am familier woth the software.I have designed the model for my both proposed project, however the detailed design is on Food delivery tray.
