face making

hello I am trying to “draw” the outside of a picture of a gun but when I am finished, and the finished vert is joined, I push F and push auto face and nothing happens. What do I have to do?

Im taking I guess hre, and assuming you’ve got an outline of vertices.
If you press F, it would make a face, IF you had 4 or 3 verts select.
3 makes a triangle, 4 makes a quad.
If you want a quick fill, I believe its SHIFT-F, and it fills it in with triangles.
It wouldn’t look pretty, but it’ll get the job done,
I don’t like modelling that way, how about you try from a cube, and extrude out faces where you need them?
