Hey! I need to cut the arms off, and maybe preferably the head as well off a heroforge stl for purposes of making painting later on easier on myself.

I'm a complete beginner with blender, so is there a relatively easy way to just cut the arms off or do I have to go in and select every face and then separate the objects. Because I've done that and I still have a bunch of little pieces that I missed due to being super small. It seems like the model is all one object, rather than smaller arranged together. I'd check for like a skeleton where i could maybe move the model a bit, but idk how to do that or if it would even help.

Pretty frustrated because I really like disassembled minis for painting, but heroforge comes assembled and its just a pain the rear. Help me dismember a little digital man before he becomes a little resin plastic man.
