Many, many times I have created a header, arched it, and used the Freeform tool to "splay" the ends; that is, drag the lower left corner downward to make the left side taller, and the same on the right. Choose the Freeform tool, click the bottom left corner and drag downward, hold the shift key to constrain it, the the same on the right. I upgraded to CC 2020 a couple of months ago, and this is the first time I've tried it, and I just can't make it work, nor can I find a tut for it. Anyone?
