Why Is 3D Modelling Used?
How and why is 3D modelling used to create a roller coaster?
Why is it used?
3D modelling is used to make roller coaters so that you can make changes very quickly and easily, rather than making the whole thing and realizing that there is a mistake in it (you would have to start it all over again!).
How does it help?
Also, it will help you to know whether the ride is intense for the person riding it or if it is too boring. It also helps you to imagine what the roller coaster would look like when it is made.
