Manipulate T-Spline edges with a driving curve

Learn how to use the Edit By Curve tool to manipulate T-Spline edges using a driving curve in the Form contextual environment in Fusion.

edit by curve example

In the Design workspace, Form contextual environment, select Modify > Edit By Curve .
In the canvas, select a set of connected edges on the T-Spline body.

A driving curve displays in the canvas.

Note: The selected edges cannot be a closed edge loop.
In the Edit By Curve dialog, adjust Degree to display 1-7 degrees of control (2-8 control points) on the driving curve.
Select the Distribution type:
- Uniform
- Edge Length
Optional: Check Planar Curve to create the driving curve on a best fit plane.
Select the Curve Fit from the dropdown menu:
- Control Points
- Surface Points
  
  Note: Adjust the Display Mode to see the effect of Curve Fit more easily. Use Box Display for Control Points and Smooth Display for Surface Points. Control Points (curve fitting only) performs faster than Surface Points (curve and surface fitting).
Click Select next to Curve Control Points.
Select the control points you want to adjust.

Note: Hold Shift to select multiple control points.
Use the distance, planar, scale, and rotation manipulator handles in the canvas to adjust the control points, or enter exact values in the dialog.
Click OK.

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

Tips

Scale and rotation manipulator handles only display when you select more than one control point.
Double-click an edge to select it and all of its connected edges.
After you select the first edge, hold Shift and click to select additional edges.
After you select two disconnected edges, press Alt+M to select all of the edges between them.
After you edit the selected edges, click the X next to T-Spline Edges to clear the selection and save the changes. You can then select and edit another set of edges before you finish the tool. Each of these operations is tracked separately, and displays in the Undo history.
