# All About 2D and 3D in Detail

AutoCAD is a popular CAD/CAM Drafting application that is used to create drafts for various industries. Understanding the basics of  2D and 3D is a good way to get started with AutoCAD. So, let’s get started!

2D is the term for “two-dimensional” while 3D is the term for “three-dimensional.”

### Aspects of 2D and 3D

A 2D shape refers to a figure with only length and height. 2D shapes are often called plane figures of plane forms. They have areas but 2D shapes don’t have volume.

A 3D shape has more than just length and height. It also has width and depth.

### Mathematical Definition of 2D and 3D

A 2D figure in mathematics and physics is drawn on two axes: the x-, and y-axes.

A 3D figure, on the other hand, is plotted on three different axes: the x- and y-axes.

Examples of 2D and 3D

The most popular examples of 2D shapes are the circle, rectangle, square, rectangle, and pentagon.

### 2D SHAPES-

Some of the most popular examples of 3D shapes are cylinders, pyramids, and cubes.

## Summary of the differences between 2D and 3D

The shape is either two-dimensional or 2D. It has both length and height. They are also known as plane shapes and can be plotted on graphs using the x- or y-axes. The most popular examples of 2D figures are squares, triangles, and circles.

The shape is 3D, or three-dimensional. It has length, width, and height as its dimensions. Mathematically, 2D numbers are plotted on graphs’ x-,y-,and z-axes. Some of the most popular examples of 3D shapes are cubes, pyramids, and cylinders.

Most commonly, the terms “three-dimensional” (or 3-D) or “two-dimensional”, (2D or 2-D), are used in photography and graphic image technology such as animation and computer graphics.

3D images have the illusion of depth, while 2D images lack this effect. On the other hand, a 2D image has only height and width. Sometimes, the term “three-dimensional”, also refers to a physical item, such as a mobile or sculpture, which can be called three-dimensional art. This is in contrast to a two-dimensional painting.

It is impossible to create three-dimensional imagery without duplicating the effects of two eyes working together. This allows for depth perception and other perceptive effects. This was possible with early 3D technology that used dual-camera and dual-lens setups. Modern computer technology is capable of creating realistic effects in both 2D & 3D.

For a moment, think about what it means for two dimensions. We could only move forwards or backward in a line if we only had one dimension. A line is only one-dimensional. A line can only be moved forwards or backward in two dimensions. We could also turn in any direction to create a new line. A flat surface is a place that allows us to travel.
