What I've learnt today

Today I learn about safety in 3D modelling and why people use 3D modelling on computers before they build the actual object. People need to use simulators and 3D design programs so that the can see if something will work or fit in place in a place or room for example a kitchen. Also if they are doing a ride or a vehicle they might have to check if it is safe to use and ride by using a simulator.
3D modelling is very useful for designers too because if they are designing something like a car they need to be able to see if the parts will all fit in the car and if they need to shrink it a few inches or even make it bigger. 3D modelling is used in lots of places like apple, BMW, Pixar, Addidas and many more to see they item or object before they actually buid or produce it.
