why do major companies mess around with all these simulators

allot of big and small companies alike use simulators before they make a real life version of something.

Why waist time

It can cost a lot of money to build a car and then find that when you've got it there is a problem with it and it doesn't work properly. 3D modelling allows you to make a pretend version of it that you can then see if it works or not and tweak it without spending much at all.

Companies who use 3d modelling

3d modelling can be easier and more precise than drawing.

Anyone can make a detailed picture on 3d modelling even if you are hopeless at drawing so it gives more people a chance at being able to make precise models
