Let me explain it, when either you extend one or joint two surfaces, SURFCAM doesn’t modify the original, it creates a new surface with the requested feature and deletes the “original surface”. This works in several commands, like Extend, Joint, Break, Trim.
You may try this: pick any surface, “Extend” it by some amount, lets say .200“, edit the color of this surface, and then select “Undelete Last”; you’ll retrieve the first surface in original color.
I know that the Undo function will be nice, but in case of a mistake, or picking the wrong side of a surface, this procedure will bring you back in a matter of seconds. Then you'll never have the feeling to be late again.
Kind regards
