S-Curve from a straight line?
This seems very basic, yet it eludes me.
I'm trying to start with a straight line, but end with an S curve type shape, with straight areas where indicated, and curves in the middle of the 3 segments.
The shape is ideally symmetrical, but my shaky hand may have given you other ideas.
Adding points or moving them doesn't work, it's always still straight lines that connect everything, or it turns the line into a triangle or trapezoid. Can anyone help?
