Head hacking help

So basicly I can’t get the head off the body of this model and would really like to. If I try and delete any part of the model, the whole thing is gone.

it would really help us if you showed pictures and what model you are trying to get the head off of.

I will later, it’s on my other computer. For now I should let you know that the model I want the head of is from the workshop, and is a playermodel, could any of that affect it?

(Btw, this is the model from the workshop http://steamcommunity.com/sharedfiles/filedetails/?id=468555886)

You have to element select the rest of the model except the head and then delete it.

I’m sorry, but, how do I do that?
