I want to do exactly what ‘Shakespear’ is doing in this video: https://www.youtube.com/watch?v=bzwybr65I9o&t=17m30s
That is, I have imported a mesh (from 3DF Sephr in .obj format) into blender. I now want to turn that flat mesh into a solid object ready for 3D printing.
Shakespeare does this by cutting a cube in half using a mesh. But this operation does not work for me as it does in the video. Actually, what happens for me is what I would expect from a Boolean intersect operation - I just end up with a flat mesh again.
So how can I turn this flat mesh into a ‘solid’ 3D object?
