1)yeah all models(once you imported them to med they are all same, right?)
2)bug, guess it will be fixed.(im not %100 sure if there is something new)
im not a modeller but
3)i use med for basic modelling, and blender for bigger models. For more complicated stuff... i can't model them at all

I had some 3dsmax educational license and was using it but i dont have it anymore. For character rigging i use med.
