In Tinkercad we group shapes to combine them, this is called a Boolean operation, which is a mathematical term. If you’ll use a box and a sphere as an example. You can combine these two shapes in a couple of different ways. Adding two shapes together is called a union. Using hole shapes, we can create a subtraction.

This much we have already discussed in previous topics, here we will discuss about one more type of Boolean operation called an intersection. It’s a calculation of the space that both shapes take up. To understand this let’s explore the related activity.
