What is a 3D CAD drawing?

3D CAD (3-dimensional computer-aided design) is a technology that engineers, product developers and designers use to create functional, virtual prototypes of three-dimensional objects. With 3D CAD, designers can dynamically create and modify every detail of a product, part or assembly.

How is CAD drawing different from a 3D drawing?

2D CAD is a two-dimensional Computer-Aided Design, 3D CAD is a three-dimensional Computer-Aided Design. 2D is a display of length and height on a plane without depth. While 3D is defined as 3-dimensional drawings or models they described objects with height, width and depth.

What is mean by 3D drawing?

To draw in 3D simply means to depict something that has volume or space. This can be as simple as adding thickness to block letters or as complex as trying to depict a cityscape or a human body in space. A drawing is a 2D model of 3D space if you want it to be.

What is the difference between 2D and 3D CAD drawings?

2D CAD is two-dimensional computer-aided design, 3D CAD is three-dimensional computer-aided design. 2D is to display length and height information on a flat surface without depth. Although 3D is defined as 3D drawings or models, they describe objects in terms of height, width, and depth.

Why is 3D drawing better than 2D?

In 2D, you can’t create images that are realistic and captivating enough to use as marketing materials or to display how a concept functions in the real world. 3D modeling software allows individuals to create photorealistic renderings of their product designs that look good enough to be published in a magazine.
