What's wrong? Or again, Match Edge is not a real feature? Thanks!
1. The smaller face (RIGHT) is created with a tunable Spline (3) and G0 at all edges. The resulting face is then matched to the larger face.2. When the Spline (3) is modified, the Match Edge fails to update!3. Delete the Match Edge (Match Edge (6)), and create a new one (Match Edge (7)). It works again.
