To split an object perfectly in half using a plane, use the Boolean modifier method with a Cube instead of a flat plane. This prevents "open mesh" calculation errors and ensures both halves remain solid, closed shapes.
Step 1 - Place Your Cube
- In Object Mode, press Shift + A ➔ Mesh > Cube.
- Scale and position the cube so one of its faces aligns exactly where you want to split your object.
- Ensure the rest of the cube completely covers the half of the object you want to separate.
Step 2 - Create the First Half
- Select your original object.
- Go to the Modifier Properties tab (blue wrench icon).
- Click Add Modifier ➔ Generate ➔ Boolean.
- Set the Operand Type to Object.
- Set the Operation to Difference.
- Use the Eyedropper tool to click and select your cutting cube.
Step 3 - Duplicate and Create the Second Half
- Press Shift + D to duplicate your object, then right-click immediately so the copy stays in the exact same position.
- Select this new duplicated object and look at its Boolean modifier.
- Change the Operation from Difference to Intersect.
- Hide your cutting cube (H) to see the results.
