Hmm, it works for me producing the .plt file on Linux and reading it there.
I can't check on Windows as the 98 box I acquired a while ago doesn't even
get to the BIOS screen these days when I power it up...

Can you send me the .plt file you produced, and the .3d file it came from so
I can inspect them?  The .dxf file might be useful too if you have that to
hand.

Which "my box"?  The Windows or Linux one?

This sounds like a portability bug in the PLT writing code in cad3d, or
possibly in the main code if the .dxf output is broken, but you said that
was OK for a small cave.

That's very bad - the plt file reading code should always return an error
whatever the input is.
