There is this thing that drives me nuts. You know that thing?

When I creating a new toposurface, I am allowed to copy "Boundary Point" outside the surface, automaticly changing the original point to "Interior Point". But, when I wanna do the same thing to a surface that was previously splited using "Split Surface" tool, I get this message:
"A Point is outside of the Surface boundary. Insert the Point on the boundary instead, and then drag it to the desired location."
I don't have time to do this. I just need to copy all the boundary points and offset them by 10 cm. Is there any way to defeat Patrick?
