Join Children: Joins the two semiproducts resulting from a vertical/horizontal cut to form a single semiproduct by deleting the cut. Two semiproducts can join together if:

· They are both final semiproducts and at least one of them is an offcut, or

· - They are both distributing the same part with the same repetition in the cut direction.

Exchange children: Exchange the two children semiproducts modifying the location of the cut in the parent semiproduct.

Extend cut: In a sequence of several consecutive cuts being all at the same direction, this option transfers the cut in the selected (parent) semiproduct to the cut in its right/top child extending the dimension of the original cut.

Diminish cut: This option is symmetrically the same as the above one but now transferring the original cut to the left/bottom child semiproduct  diminishing the dimension of the original cut.

Cut to horizontal: When a parent semiproduct is:

- vertically cut and one of their children is horizontally cut and the other is an offcut, or

- both children are horizontally cut at the same dimension,

parent and children cuts are exchanged so that the parent semiproduct and their two children are now left, respectively, horizontally and vertically cut.

Cut to vertical: This option is symmetrically the same as the above one but for horizontally cut  semiproducts.
