Hole
A cube-shaped object that is pre-configured to act as a boolean subtraction tool. When you use Combine, Hole objects are automatically subtracted from other shapes instead of being added to them.

How It Works
The Hole primitive works like a Cube but has its output type set to “Hole.” When you combine objects that include a Hole, the Hole’s volume is removed from the result.
Parameters
Same as Cube:
- Width - Size along the X axis
- Depth - Size along the Y axis
- Height - Size along the Z axis
Tips
- Position the Hole so it overlaps with the object you want to cut
- Make the Hole extend completely through the target object if you want a through-hole
- You can use regular shapes with Subtract for the same effect, but Holes are convenient because they work automatically with Combine
- For round holes, use a Cylinder with Subtract instead
