They use models to test their designs of new technologies.
Engineers put very accurate models of new airplanes in wind tunnels to see how aerodynamic they are.

Civil engineers do use jackhammers to break-up old roads and put down new ones.
Because they can find a lot of information about it's flight characteristics in wind tunnels.

Computer engineers must find all the unanswered questions of other engineers and design new models.
Catia is a 3D Modelling Software from Dassault Systemes, France. It is required in various Mechanical and Aerospace applications. Design Engineers create 3D models, Surfaces, Assemble various Part models etc.

CAD is an acronym for Computer Aided Drawing. Engineers use it to create visual models of the project and most times the information can be transmitted to another machine for fabrication.
First they take the measurements of the model and use the scale (ex. 1:10, 2 cm: 13 km, etc.). Depends mostly on what they are building and how big they need it but it's all ratios.
Engineers use blueprints so that they can see what the height and width of a object is going to be and how to make it.
