this page mainly focuses on a website called sketchup so, Sketchup is a website that you use to make different things like buildings and houses like the one below. SKetchup helps you to see what is in your head and bring it to life, and it is the exact measurement as it would be in real life if you were to make it.
To make the house below I had to use sketchup.
The picture to the left was made in sketchup while the one on the right is the same thing but after sketchup i put it into blender and made what you see now.
