Hi Necko, I have fixed up one part of the problem that was preventing this PDF from being read, I have attached a 3DM version here.

But as you can see, it is upside-down so I'm going to look into a little bit more to see if I can fix that as well. For now you should be able to mirror it to fix it up.

The other thing is that I guess this PDF was probably generated through one of those PDF printer drivers? That usually creates a side effect that all curves are broken up into line segments, so just be aware of that.
