I've loaded several MDLs into an empty level in WED. I rearrange the MDLs (floor-MDL, wall-MDL, entrance-MDL) so they "fit together". (I realize that I could also do this in MED, but I find it easier in WED)

I then try to EXPORT to MDL from within WED.

I've checked the box for "include MDLs".

The export routine does indeed generate the specified MDL, but when I call it up in MED, there's no geometry - under object properties I see only "1 group", but nothing else.

I've tried various combinations of checks (selecting the MDLs and then exporting "only selected", "merge all" etc.) but I keep getting an empty MDL.

Does anyone else have any clue / experience with this ?

Cheers,
Andreas
