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.
