Unfortunately, there isn’t an easy button to push in Tinkercad to make intersection shapes. So, we need to do it in a few steps.

Step 1: Take a box and a sphere.

Step 2: Align them together as shown. You can use Align tool also.

Step 3: Click on sphere and change it to the hole.

Step 4: Group them.

Step 5: The shape will be look like as shown below. Change this resulting shape to hole.

Step 6: Drag another box.

Step 7: Align them as shown either use mouse or use align tool.

Step 8: Group them.

And now we have that intersection dice shape.

Making intersections in Tinkercad requires you to think a little outside the box, but it’s a great way to start thinking about how to create complex objects.
