How to Cut and Key 3D Models Using Boolean Modifiers

In this tutorial, we will demonstrate how to cut and key 3D models using boolean modifiers in Blender. By following these steps, you can effectively create separable parts for your 3D prints. Let's dive in!

Preparing the Model

Before we begin the cutting process, there are a few essential steps to ensure a smooth workflow:

Apply Rotation and Scale: Select your model, go to Object > Apply > Rotation and Scale to avoid any issues during the cutting process.
Set Origin Point: It's advisable to have the origin point at the center of your model. You can achieve this by going to Object > Set Origin > Origin to Geometry.

Creating the Cutting Plane

To initiate the cutting process, follow these steps:

Add a Plane: Insert a plane, scale it up, and position it accordingly.
Solidify Modifier: Give thickness to the plane using the Solidify modifier. Adjust the thickness as needed for 3D printing.

After applying the solidify modifier, proceed with boolean operations to cut the model effectively.

Cutting and Keying the Model

1. Cutting with a Cube

Difference Boolean: Use a cube as your cutting object. Apply the Difference boolean operation to cut the model.
Separate Parts: In Edit Mode, select the separated parts and split them into individual objects.

2. Organic Cut Using a Single Vertex

Shrink Wrap Modifier: Create a single vertex and add a Shrink Wrap modifier with the dog model as the target.
Extrude and Scale: Extrude the vertex around the model and join the points.

By carefully following these steps, you can achieve precise cuts and keys in your 3D models, essential for various design and printing purposes.
