Match T-Spline edges to solid, surface, or sketch geometry

Learn how to use the Match tool to align the edges of a T-Spline body with sketch curves or edges on a solid or surface body in Fusion.

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

2. In the dialog, check Associative to create an associative relationship between the T-Spline geometry and the parametric solid, surface, or sketch geometry.

3. In the canvas, select a set of T-Spline Edges to form the first side of the match.

4. Select sketch curves or edges on a solid or surface body as Match Edges to form the other side of the match.

   A preview of the match geometry displays in the canvas, spanning between the T-Spline Edges and the Match Edges.

5. Optional: Adjust the Continuity across the match transition to faces on a solid or surface body:

   • Connected (G0): Applies G0 positional continuity.
   • Tangent (G1): Applies G1 tangent continuity.
   • Curvature (G2): Applies G2 curvature continuity.

6. Optional: Adjust the Spacing to control the distribution of control points along the match edge:

   • Uniform: Distributes control points evenly.
   • Curvature: Distributes control points based on the curvature of the match edge.

7. Click OK.

The adjusted edges display on the T-Spline body in the canvas.

If the match is Associative, when you modify the solid, surface, or sketch geometry in the parametric design environment, the T-Spline edges adjust to maintain their relationship with the match edges.

Tips

• Check Associative to create an associative relationship between the T-Spline geometry and the parametric solid, surface, or sketch geometry.
• If the geometry between the T-Spline Edges and Match Edges intersects itself, click Alternate Alignment to switch the direction of the control points around the match edge, clockwise or counterclockwise.
• Use the Tolerance settings to control the deviation of the T-Spline edge from the match edge.
• Use the Falloff settings to control how much of the T-Spline is influenced by the match.
• Drag the control points along the match edge to fine-tune the alignment.
