How can I change the radius of a rounded corner afterwards?
I have rounded my PCB outline at all 4 corners. But now I want to change the radius of the roundings. How do I do this?

It is best to first convert each rounding back into a real corner and then make the rounding again:

1 (Fig. 1: Convert rounding back)

To do this, select the arc and then use the context menu of the small black box with M2.

Then round the corner with a new radius:

2 (Fig.Round corner again)

To do this, select a line and also use the context menu of the small black box.
