How do you add single free floating vertices as primitives at a given XYZ coordinate postion I am sure this question has been asked before but I have searched and searched and I can't find it (I even vaguely remember asking it in 2013 5 years ago). 

I am easily fooled by perspective illusions, and prefer to plot rather than to sculpt, in 3D, because of this. 

Is there a way I can make single vertices a primitive in the primitives menu, like that darn monkey (long live suzie), so that I can place a bunch of points in a row with minimum effort, and then connect them and create edges and faces at the end?

I vaguely remember reading about a potential plug-in solution, but that was quiet a while ago, and I can't find my source, so I'm totally lost
It was the Extra Objects addon.

I was going to use it to create a point primitive, so I misrembered it and used the wrong keyterms while searching for it. 

I did have a neat/convenient idea while trying to figure this one out, I'm not sure if that's a seperate question or just an alternate solution though (about the point plotting box). 

So if something like that exists [the enmasse point plotting box], feel free to comment it to me, if it doesn't then I guess I'll have to ask/or/find some more questions later [about making plugins, and creating a tiny little app/menu for that in blender]
