I’m a newbie with Rhino and just learning to use Rhino with Orca3D. I have created this hull shape using Orca. I want to shell this hull (add thickness to walls and remove the top (deck)). I have tried joinining the surfaces and running the Shell command, as well as deleting the top and rear (transom) surfaces and running the OffsetSrf command. Both times I get error messages in the console.
Failed to shell one polysurface.
Failed to offset 1 surface.
I believe I’m having trouble from the hull surface itself (the curved one) as opposed to the top (deck) or the rear (transom) surfaces as they are flat.
I undid the join command before uploading the file since I’m not sure if one can access the surfaces one by one after joining.
What might be wrong with the surfaces that might prevent shelling it? I’m trying to achieve a wall thickness of 50mm although I have tried other (bigger and smaller) values.
