How do I edit a contour type segment such as spline?

Support
1

I drew a segment using splineTool, but if I only want to add or remove, I don’t know what value
I need to modify.

I would appreciate it if you could tell me if I can apply FreehandTool or LivewireContourSegmentationTool in the same way.

please help me…

I don’t understand the question. Could you please elaborate, ideally with screenshots or videos?
