In all other situations the pattern should be repeated at the backside of the object's wall if it needs to be visible from the inside.

fyi: LDCad will render the whole part dual sided when noclip is encountered anywhere in the recursive mesh data.
I noticed that the other day. I had a part (772p01.dat) that I tried adding the NOCLIP statement to, but it changed the rendering of the whole part, not just the geometries between NOCLIP and CLIP.
So, in LDCad, the intened way to view patterns from both sides of a transparent part is to disable "Use BFC info if available"? That of course affects not only the transparent part, but all other parts in the model (though I'm not sure what effect this would have on rendering non-transparent parts, other than affecting system performance).
Or should we enable "Two sided transparency"? Again, that affects the entire transparent part, not just the pattern geometries—and i a slightly different way than disabling BFC. I suppose that's probably the point, although I visually prefer the rendering when neither of these options is used (except for being unable to see the reverse sides of patterns).
