Cut and slice polygons with the Modeling Toolkit

The Modeling Toolkit Multi-Cut tool combines the functionality of three different tools into one. You can cut, slice, and insert edge loops when the Multi-Cut tool is active.

To cut a polygon mesh

The cut function lets you split polygon faces by drawing a line across a face to specify the location of the split.

1. In the Mesh Editing Tools section of the Modeling Toolkit window, click Multi-Cut to activate the Multi-Cut tool.
2. In your scene, click the point on your mesh where you want the split to begin. Split points can be on edges and vertices, and in the middle of faces.

   A yellow split point appears.

   TipUse the following tips to adjust split points:

   • Press Backspace to remove split points.
   • Hold Shift to snap split points along edges. You can adjust the snap interval in the Snap % field in the Multi-Cut Options.
   • Drag to reposition split points that are placed on faces. (When you reposition a split point on a face, you're constrained to the surface of the single face.)

3. Click another edge, vertex, or face to define the second split point.

   A second dot appears and the two split points are joined by a green dotted line.

   TipYou can insert split points that are several faces apart. The cut will automatically span across all components.

4. (Optional) Continue to define points to split many polygon faces.
5. Press Enter to bake the split into the mesh.

To slice a polygon mesh

The slice function lets you cut faces perpendicularly to the view plane.

1. In your scene, click anywhere outside the mesh to define the first slice point.
   TipYou can also click-drag to create the start and end points of a slice.
2. Use the following tips to adjust slice points:
   • -drag to move a slice point after it is dropped.
   • Drag to reposition slice points placed on the surface of a face.
3. Click in your scene again to define the second slice point.

   A second dot appears and the two slice points are joined by a green dotted line.

   TipDrag across the mesh to automatically create a cut.

4. (Optional) Do either of the following to edit the slice plane:
   • -drag the slice plane to reposition it.
   • Shift-drag a slice point to reposition it.
5. Press Enter to slice your mesh.

   All of the faces are cut along the slice plane.

To insert an edge loop

1. Do one of the following to insert edge loops:
   • -drag to insert an edge loop anywhere on your mesh.
   • + -drag to insert an edge loop that automatically snaps to the middle of the edge ring path.
   • + -drag to insert an edge loop that snaps to the edge ring path according to the Snap % interval. See Mesh Editing Tools
