Slice faces with the Multi-Cut Tool

You can use the Multi-Cut Tool to slice polygons along a straight plane, and then extract or delete faces above or below the cut.

To slice a mesh using a custom plane

1. Select the mesh you want to slice.
2. Open the Multi-Cut Tool.
3. Click on either side of your mesh to define two slice points.

   An orange slice preview line appears between the slice points. This line represents the slice plane.

4. Edit your slice plane by doing the following:
   • Middle-drag to reposition the plane.
   • Drag to reposition slice points.
5. (Optional) In the Modeling Toolkit window, select Delete Faces or Extract Faces in the Slice Tool options.
   A dotted line perpendicular to the slice preview line appears, indicating the side of the mesh that will be deleted or extracted.

   
6. Press Enter or right-click to cut the mesh along the slice plane.
   

Alternatively, you can use a quick slice if you don't need to edit any points or toolkit options.

To quick slice a mesh

1. Select the mesh you want to slice.
2. Open the Multi-Cut Tool.
3. Middle-drag anywhere on your mesh to make a cut.
   

Finally, you can slice across a predetermined plane using the Slice Tool options.

To slice a mesh using a predetermined plane

1. Select the mesh you want to slice.
2. Open the Multi-Cut Tool.
3. (Optional) In the Modeling Toolkit window, select Delete Faces or Extract Faces in the Slice Tool options.
4. Click one of the Slice Along Plane buttons.

   The mesh is sliced along the selected plane, and a manipulator appears.

5. Use the manipulator to adjust the slice.
