I have been trying to offset my object so it has a thickness so I can continue modeling but I still couldn’t find any solution for it now (I also tried Maya, but I’m not really familiar with it. Edit Mesh_extrude_, but it still not working).
The model scale is about 200’*300’ with a thickness of 6".
These are some of the photos that I failed offsetting.
First picture is the whole model, second one is what it turned out.
Even I cropped out a little piece to try if it would work. (the first picture is the piece, the second is how it turned out)
