In the bottom third of both tabsheet registers, there are four boxes representing options for the cut itself. By ticking or unticking these boxes, you can activate and deactivate the options.
You can cut only selected parts or all parts, through which the cutting plane or line runs. Selection options are the same as in the standard module.
When you use the plane boundary, the cut is only conducted as far as the outer edges of the plane go. If the box is not ticked, the parts are cut completely through along the plane, independently from the size of the displayed cutting plane. This option can only be chosen for cuts with a cutting plane.
If you Stitch parts, open triangle edges are connected. Sometimes, if the option Triangulate Cut is activated, the cutting tool produces open edges (for example if a part has self-intersections) which can be connected with this additional step.
Next, you can choose to Remove the original parts and replace them by the cut parts. If you do not remove them, they are hidden after the cut.
If you triangulate the cut, holes that emerge at the new cut parts are closed automatically with a straight surface across the cut. If not, the parts will be open.

With the option Create group, the cut parts are moved into a new group in the project tree. Finally, at the bottom of the tabsheet, you can either Cut to perform the cutting with the chosen plane and settings. The cut parts are then inserted into a group in the project tree. You can also cancel the cutting and leave the cutting tool without doing anything. You can go back to the tool any time. The cutting plane remains in place.
