Change link to arc converts a selected segment to an arc that has the same shape. This does not change the shape of the surface but you can use it to control surface behavior between defining curves, for example.
To use Change link to arc:
- In the Modify Surface dialog, select Change link to arc.
- Select a surface from the Surface list, or click the Pick Surface
button and select it in the graphics window. - Click the Pick curve on surface
button and select a curve in the graphics window. - Click OK.
The selected segment is converted into an arc, and the surface shape is recalculated.
This edit breaks the link between the surface and the method originally used to construct it. You cannot open the surface's Properties dialog and modify it based on the parameters that originally defined it as those parameters no longer apply directly to this surface.
