How can you create smooth blended surface in CATIA?

To create a smooth blended surface in CATIA, you can use the Blend feature. Here are the general steps to create a blended surface:

1. Open the Blend1.CATPart document.
2. Click on the blend icon to open the blend definition dialog box.
3. Successively select the first curve and its support, then the second curve and its support.
4. Set the continuity type using the Basic tab, which defines the continuity connection between the newly created surface and the curves on which it lies. This can be set to tangency, point, or curvature continuity types.
5. Activate the trim first/second support option, on one or both support surfaces to trim them by the curve and assemble them to the blend surface.
6. Set the tension type using the tension tab. It defines the tension of the blend at its limits. It can be constant or linear and can be set for each limit independently.

These steps allow you to create a smooth blended surface between two wireframe elements, considering various constraints such as tension and continuity.
