Make Holes with an Object in Blender
In this article we see how to make holes in Blender using the “Boolean” modifier in “difference” operation mode, this allows us to remove the volume that occupies a second piece inside the object.
In the following video you can see how I make a hole in an object using this method.
Procedure for making holes in Blender
We are going to take a cube and make a hole in it using a cylinder, as shown in figure 1.
Select the cube and go to the “Modifiers” tab, shown in figure 2. Then add the Boolean modifier, as shown in figure 3.
In the “Object” field of the modifier we have to assign the object that is going to make the cut, in our case the cylinder. We can use the eye dropper to select the cylinder or we can choose it from the list.
The operating mode must be “Difference”, so that all the space occupied by the cylinder inside the cube is eliminated, as shown in figure 4.
Then we place the cylinder where we want the hole to be made.
If we go to the Outliner and hide the cylinder (figure 6) we see that the piece has already made the hole.
When we don’t have to make any more changes, we can apply the modifier to make the cut effective. In figure 9 we see how the geometry looks after applying the modifier.
