Hi!

Try this.
In the 3d window of MED rotate your model until you see the 2 polygons in full front view
Select the 2 polygons and lock the selection (They are facing you)
Edit --- Create 6 sided mapping ---Custom --- ok (close)
Go to the skin Editor
You should see this part of your model in selected mode.
Resize
Move to a free area
You should now be able to skin this area.


Let me know if this was the solution
