Carve topo as pocket

Trying to put topo map of a lake into a bowl,want to carve the pocket so that I can profile the bowls exterior.. Boundary relief does not work, Boundary relief would work if it could be set at zero or near zero depth, just so it skimmed a little off the area ajacent to the topo pocket.
Relief works for an Island as you can have the ocean around the topo map, tho’ it would be nice to be able to adjust the inside rim of the bowl other than boundary or rectangular relief.

Been trying to do this for more than a year now.

You need to make this public in order for people to see it.

Thank you, I think I just made it public, not sure if I did it correctly.

so you want that shape within a bowl? Like at the bottom of a bowl? What kind of bowl? Globe shape? Shallow like a serving bowl. I think you will need to make the bowl shape and then add the lake to it. If you explain this better and send me the file above, as I don’t use Pro, I might be able to pull it off.
