I need to have a closed polysurface with surface direction outwards on my boat hulls to be able to use model information in subsequent plugins/software.
I can manage to get the individual surfaces to have correct direction, but when I join the last surface, I often end up with a closed surface with direction pointing inwards - i.e. direction of all surfaces have been flipped
Most of the time, I can bypass this problem by trimming the “non-essential” part of my hull (a distance above waterline) and close the polysurface by means of cap command or an imaginary deck surface.
However, for some models, I cannot manage to create a closed polysurface with direction pointing outwards, no matter what (limited) surface tools I try.
Does anyone have an idea what causes this, and how to avoid it / workaround??
PS! Due to client agreement I cannot upload model files
