@VectorStyler My first reflex was indeed the "delete" key. I should have thought about it and stayed on this problem but as I was trying to reproduce with VS what I did more than 10 years ago with AI, I was already thinking about what other effects I was going to affect, wondering where to find them, etc. I wanted to come back to this problem but the transformation of my blended object crashed VS. On restart, a crash report has been sent (had to be sent).
The habit of working with AD where the deletion of such points is also done by the delete key.
It would be nice to add this possibility for all curves.
