Boolean Operations with Slices
If two or more slices are selected, you can perform Boolean operations within the Slice Commander. These allow you to merge overlapping slices, create an intersection, or subtract one slice from the other.
You can find the option in the context menu after right-clicking on one of the selected slices. A dialog box appears in which the selected slice files can be assigned to the two fields "Add" and "Subtract". At the beginning, all slices are in "Add". If you click on a slice and then click on the arrow pointing to the other field, the file is moved there. If you click on the X, the selected file is removed.
To unify slices, all slices have to be in the left field "Add". Execute the unification with the button "Boolean".
If you choose the option Merge Slices in the context menu directly, they will become one slice as well, but overlapping contours will remain without being unified.
For an intersection of selected slices, choose "Create Intersection" in the context menu instead of "Boolean Operation". The resulting slice includes only the overlapping sections of all selected slices.
To subtract slices from others, you have to move those files you want to subtract into the right field in the dialog box of the Boolean operations. The software creates a unification of all slices in the "Add" field and subtracts the area of those slices in the "Subtract" field from that unification. Overlapping areas are deleted

To immediately see the result of the Boolean operation, tick the box Preview Calculations in the tabsheet (=default). The calculations are applied automatically when you export the file or with the function "Apply calculations" in the context menu (see here).
