Lesson 3-2 Isometric Drawing
Isometric commands is one of the easiest ways to give a drawing in 2-D a 3-D look. Isometric drawing was the standard way of drawing 3-D before we were able to do true 3-D work. An isometric drawing is not true 3-D.
The CAD command ISOPLANE allows one to easily draw an object at 30 degree angles needed fo isometric drawings.
Lesson 3-3 Working in 3 Dimensions
We are used to just using 2 axis. when working in 3 dimensions a third axis is introduced, the z-axis. the axis represent the height, length, and depth of an object.
Lesson 3-4 Viewing 3-D Objects
In CAD you can use view ports to to more easily see all the sides of your object. there are viewports for the x axis, y axis, and z axis.
Lesson 3-5 Basic Wire Frame Models
Wireframes are the simplest way to display 3D objects. They are like a skeleton of the object, and allow you to look through and see other edges.
