Hey Everyone,
I am trying to create the silhouette of a bay for a friend. I have everything setup, however when I go to setup the tool paths it wants to cut out what would bee the land portion and not the water portions (see below).
I have attached the c2d file, if anyone can offer any assistance it would be greatly appreciated.

The relevant concept here is “Figure-Ground Reversal”
You will need to change which parts are connected/closed, so that rather than a landmass:
as a closed object, the selection would be of all the water areas defining the water area as a closed region.
This may be done by Node Editing:
Doing this along the length of each straight line along the artificial border:
Continue removing nodes until no straight geometry is left:
Repeat for all other regions, eventually arriving at:
which should then be closed to create the desired region:
Yes
Where things don’t join:
Draw in geometry to allow things to close:
Then select:
and use Join Vectors:
Repeat as necessary until one arrives at:
which may now be assigned an Advanced V carving toolpath:
and a rectangle drawn in as a border:
Attached as a v7 file.

Note that the original geometry is on a hidden layer:
