Creates a new blend curve between two existing curves.
How to use
1. Click the Blend curves icon or choose the Tools > Curves > Blend curves command.
2. The program console prompts Pick curve #1 near endpoint.
3. Pick the first curve near the endpoint where you want the blend curve to start. Once picked, the curve turns green.
4. The program console prompts Pick curve #2 near endpoint.
5. Pick the second curve near the endpoint where you want the blend curve to end. Once picked, the curve turns green and the new blend curve is created.
Thanks to the Construction Tree even if you move and modify the two original curves, the blend curve is interactively updated and stays attached.
