The Mesh Cut tool splits one mesh into parts using a second mesh. You can use the tool to break up meshes into smaller components and add detail, reducing the manual process of adding edges and deleting faces when modeling.
Accessing the Tool
Mesh Cut is located in the Model category of Modeling Mode. To learn more about Modeling Mode and how to access it, see Modeling Mode Overview.
Using Mesh Cut
Gizmos for each mesh appear in the Viewport to dynamically change the cut.
Similar to the Boolean tool, the selection order matters as follows:
- The first selected mesh becomes the one you cut.
- The second selection becomes the cutting boundary.
Mesh Cut is a single-cut tool, meaning you must start a new session for each cut you want to make on the mesh.
Once you are done using the tool, accept or cancel the changes in the Tool Confirmation panel.
Settings
| Setting | Description |
|---|---|
| Try Fix Holes | When true, Mesh Cut automatically attempts to fill holes created by numerical errors. |
| Try Collapse Edges | When true, any extra edges created by the boolean operation are collapsed. |
| Winding Threshold | Determines whether a triangle in one mesh is inside or outside of the other. |
| Show New Boundaries | When true, shows boundary edges created by the boolean operation caused by numerical errors. |
| Use First Mesh Materials | When True, only the first mesh keeps its material assignments. All other triangles are assigned material 0. |
| Show Gizmo | Toggles the transform gizmo's visibility. |
