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.

Models give a visionary view to the problem at hand and help catching all the system aspects.
They use models to test their designs of new technologies.

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.
Engineers put very accurate models of new airplanes in wind tunnels to see how aerodynamic they are.
Engineers use scale models to visualize and test designs before full-scale construction, allowing them to identify potential issues and make adjustments more easily. Scale models enable simulations of real-world conditions, providing valuable insights into performance and functionality. Additionally, they facilitate communication with stakeholders by providing a tangible representation of concepts, making it easier to convey ideas and gather feedback. Overall, they help reduce costs and risks associated with large-scale projects.
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.
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.
