Robin,
I manually changed the file name to "Bed2.gsm" and was
able to open it in AC 8.1.
I looked at the 2D script and found several strange things.
The 2D script is as follows.

Notice that the dimensions in the POLY2_B{2} command
are all the same. This makes a dimensionless polygon.
This explains the error message.
Also notice that the LINE2 commands draw lines that have zero length.
this makes a dot at the origin.
Notice also the HOTSPOT2 commands place hotspots on top of each other
This is one giant bed. The X dimension of 17895'-8.3647" is rather large.
Clearly AC has screwed-up the auto-script.
I have no idea how, on purpose, to make AC do what it did.
Is this your second attempt to save the 2D drawing as a GDL object ?
I would try once more. But before doing so I would do a couple of things
in the 2D view.
Set the scale to one that makes sense for the size of the object.
Move the 2D elements to the project origin.
Check the dimensions of the 2D elements.
Thank you,
Peter Devlin
