The "Negative Part" feature we provide allows subtracting one shape from another to achieve a recessed effect.
Negative parts include: Cube, Cylinder, Sphere, Cone, Disc, Torus, Rounded Rectangle, User-loaded custom models.
Note: Unlike boolean operations, negative part subtraction only occurs during slicing and does not modify the geometric shape of the object. Therefore, it does not support exporting STL files that include subtraction results.
