We are going to use the 3-dimensional cartesian coordinate system. This is a geometric system in which three values or parameters are required to determine the position of an element. These parameters are referred to as x, y, z. X-axis, is left and right in 3D space. Y-axis, is toward and away from user. Z-axis, is up and down.Let’s try to recreate these dimensions with found objects! Grab some pens, modeling clay, pipe cleaners
Computer-aided design (CAD), is technology for design and technical documentation, which replaces manual drafting with an automated process.
CAD is used to design curves and figures in two-dimensional (2D) space; or curves, surfaces, and solids in three-dimensional (3D) space. CAD software is used across automotive, shipbuilding, aerospace, architecture, medical and design industries, as well as, by artists, hobbyists and us.
The software we are going to use allows us to create using basic three-dimensional geometric forms (cylinders, spheres, cubes) that have solid volumes added or subtracted from them. Two-dimensional projected views can easily be generated from these models.
