CAD: Computer-Aided design

Computer-aided design, commonly known as CAD, empowers engineers to create and engineer diverse projects across various industries. From metal fabrication and carpentry to 3D printing, CAD finds application in numerous manufacturing processes, facilitating precision and efficiency throughout the design and production stages. Modeling in both two-dimensional (2D) and three-dimensional (3D) formats, preferably with parametric capabilities.

This week has been both engaging and dynamic as I delved into designing various projects using a variety of design applications like Tinkercad, AutoCAD, among others, to fulfill my assignments.

Assignments

Our task for this week is:

Model (raster, vector, 2D, 3D, render, animate, simulate, …) a possible final project, compress your images and videos, and post it on your class page

What 2D Model? A 2D geometric model is a geometric model of an object as a two-dimensional figure, usually on the Euclidean or Cartesian plane. Even though all material objects are three-dimensional, a 2D geometric model is often adequate for certain flat objects, such as paper cut-outs and machine parts made of sheet metal. Other examples include circles used as a model of thunderstorms, which can be considered flat when viewed from above.

What is 3D Model? 3D computer graphics, 3D modeling is the process of developing a mathematical coordinate-based representation of a surface of an object in three dimensions via specialized software by manipulating edges, vertices, and polygons in a simulated 3D space.

2D design
