Flatten an area of a T-Spline body

Learn how to use the Flatten tool to align vertices on a T-Spline body onto a single plane in Fusion.

1. In the Design workspace, Form contextual environment, select Modify > Flatten .

2. In the dialog, select a Direction type:

   • Fit: Uses the best fit plane. Requires at least four vertices per surface.
   • Select Plane: Lets you select a plane to flatten all control points to. Requires at least one vertex per surface.
   • Select Parallel Plane: Lets you select a plane and moves control points to a parallel plane. Requires at least two vertices per surface.

3. In the canvas, select T-Spline Vertices on a body to flatten.

   The body flattens in the canvas.

   Note: The more vertices you select, the flatter the body becomes. If you flatten linked tangency handles, they will unlink from their vertices.

4. In the dialog, select a Flatten Type:

   • Control Points: Lets you move control points.

   • Surface Points: Lets you move surface points.

     Note: Adjust the Display Mode to see the effect of each Straighten Type more easily. Use Box Display for Control Points and Smooth Display for Surface Points.

5. Click OK.

The flattened area displays on the T-Spline body in the canvas.
