# Boolean objects

Use Boolean operations to shortcut trimming and joining operations.

## Boolean solids

The Boolean commands work best on closed surfaces and polysurfaces that intersect each other completely.

Cycle through possible Boolean operations between two objects.

Subtract the volume of one set of objects from another.

Create a new solid from solids' intersected volumes.

Split and close solids at intersections.

Combine the volumes of one or more objects.

Replace a non-manifold polysurface with all solid manifold regions defined by the surfaces of the input.

## Boolean curves

Curve Boolean operations quickly trim, split, and join overlapping curves.

Trim, split, and join curves based on their overlapping regions.

## Boolean meshes

The mesh Boolean commands work best on closed mesh objects.

Subtract the volume of one set of objects from another resulting in a mesh.

Create a new mesh from the intersected volumes of objects.

Split and close objects at intersections.

Combine the volumes of objects into a single mesh.
