This is the opening screen in CAD

This is typical view of a 2D Design on a CAD Screen

This is typical view of a Completed Design on a Paper

This is Plan View used in the Architectural and Building trade

 This is an Elevation used in the Architectural and Building trade

This is a Section Through a building also used by architects and builders  

CAD Designers Some times usese models

You can see if all the parts fit correctly

You can tack as many a section views as you like

An example of a section through on a Model

A section through is like an inpretion of an object as if you have past a thin pain of glass through it and got an inprint of the area.

Another Useful feature of using model is creating an exploded view as seen above, that an Engineer would use for example in a manual.

Interior designers often use Models
