"animate on MED" really? I think your the only one who ever suggested that :))
animate in MED is a pain in the ass. Sure easy stuff can be done, but thats it.
Now, I know how to create bones in MED and Blender.
I think you stil dont get what i mean...

I HAVE already a model with bones and animation in MED. Now i want to Import that Model (with bones and animation) into blender, so i can make better animations.

in MED there are some 3DS Export options, but i dont know which one i can use for that, if it is one any use of what i need at all.
