Trim or split a mesh body with a plane

Use the Plane Cut command to trim or split a mesh body with a plane in Fusion.

1. In the Design workspace, on the Mesh tab, select Modify > Plane Cut .

   The Plane Cut dialog displays.

2. In the canvas, select a mesh body.

3. Select a plane or planar face to use as the Cut Plane.

4. Adjust the location and orientation of the plane:

   • In the canvas, drag the distance, planar, or rotation manipulator handles to move the plane.
   • In the dialog, specify X, Y, and Z Distance and Angle values.

5. In the dialog, select the cut Type:

   • Trim: Splits mesh faces along the cut plane, then removes one side of the mesh body.
     • Click the Flip icon to flip the side of the mesh body that is removed.
   • Split Body: Splits mesh faces along the cut plane, then separates the mesh body into two mesh bodies.
   • Split Faces: Splits mesh faces along the cut plane and maintains a single mesh body.

6. For the Trim or Split Body cut types, select a Fill Type:

   • No Fill: Does not add mesh faces to close mesh body.
   • Uniform: Adds a uniform set of mesh faces to close mesh body.
   • Minimal: Adds a minimal number of mesh faces to close mesh body.

7. Click OK.

The trimmed or split mesh bodies display in the canvas. A Plane Cut feature displays in the Timeline.

Tips

• Use Plane Cut to slice a mesh body along a plane and either trim away one side of the body, split the mesh body into two separate bodies, or slice the mesh faces but leave the mesh body whole.
• Adjust the Fill Type to either leave a mesh open or close the mesh body after you cut it. You can fill the voids that the cut plane leaves behind with either uniform or minimal mesh faces.
• Right-click the feature in the Timeline and select Edit Feature to edit adjust its settings.
