Question

I am done with the scratch of my model.

A question:
What must I do with a attachment, to make it be like a attachment. Must I add an attachment point? When I am done and are going to make it into a mdl, must the model be standing like this | or lying like this _ or like this \?

 

[NhazUl]

It should be lying like _, spike forward if it's a spear, blade downward if it's an axe. The part of the handle where the wielder's hand is put should be at 0,0,0. No attachment points are necessary.
