Cuts the second cross-section out of the first, the same as subtract.
The cross-section to cut from and the one to cut with
The first minus the second
Fuses two cross-sections into one, the same as add.
The two cross-sections
The fused cross-section
Keeps only the area two cross-sections share, the same as intersect.
The two cross-sections
The shared area
Cuts the second cross-section out of the first, leaving what remains of the first.
The cross-section to cut from and the one to cut with
The first minus the second
Fuses two cross-sections into one outline, holes and all.
The two cross-sections
The fused cross-section
Keeps only the area two cross-sections share, dropping everything else.
The two cross-sections
The shared area
Cuts every further cross-section in the list out of the first one.
The cross-sections, the first being the one cut from
The first minus all the others
Fuses all the cross-sections in a list into one.
The cross-sections
The fused cross-section
Keeps only the area all the cross-sections in a list share.
The cross-sections
The area common to all of them
Combining Manifold cross-sections: fusing, cutting and intersecting two or many flat outlines at once. The two-shape and many-shape forms give the same results and exist for convenience; every method returns a new cross-section and leaves the inputs as they are.
