What is 2D CAD? What is 3D CAD?

2D CAD Drafting:

2D CAD drafting is drawing on the x,y axis. Measurements deal with length and width or height and width. Views can be cut to show a cross-section, a 2 dimensional view of the inside surfaces. Views can be shown looking down (plan view or top view) or facing the object (elevation or side view).

Typical terms for 2D drafting drawings are: Floor Plans, Elevations, Sections, Views. 2D drafting can also include Diagrams, Charts and Notes. 2D Drafting is still the most universal form of drafting and the most commonly used.

3D CAD Drafting

3D CAD drafting is drawing on the x, y and z axis. Measurements deal with height, width and depth or volume.

Typical terms for 3D drawings: 3D, 3-D, CAD Modeling, 3D Rendering, 3D Model. 3D drafting is an effective graphics tool in sales and marketing. It is used in Manufacturing (CAM) and Building Information Modeling (BIM). 3D drawings are currently becoming mandatory for many disciplines.
