This is a beziers circle after some editing (rotating the whole thing, moving points…). Could you enlight me about that:
I never noticed before, but there seems to be two types of bezierpoints. Their color are different (first image: unselected; second: selected both ) and behave differently.
Needing to add a new point between them, I subdivided the segment: the adding of a point modifies the upper point, but not the lower.
Why? What are those different types? Can I switch one to another? (actually I need to transform the upper one into the “unsensitive” type)
