I made the mistake of setting up my project extents at 100 km x 100 km. After some recalculations, it should be 68 km x 68 km. If I change the extents in the Project Settings, all my shape devices basically stay the same size and just crop themselves to the new size. I need them to downscale if possible. I could manually rescale the shape devices but something like the River device offers no scaling option and it would have to be redone from scratch.
Is it possible to rescale to new extents in World Machine?
