just 1 question how do i connect vertices i have blender 2.24
You could join them with alt + m.
WHY are you using 2.24?! We are already up to 2.36, and soon 2.37 will be coming out! :o
Or maybe you meant 2.34, in which case, you are still using an outdated version, but not so bad.
Anyway, what do you mean by “join”? As Giangmatrix mentioned already, you can merge 2 or more vertices with alt+m, and you can join 2 vertices to make an edge with “f”. (You can make faces by selecting 3 or 4 vertices and pressing “f”.)
with alt +m it just brings up the layer selector and with f it says error cant make edge/face
It should be in edit mode and you can use f only if you sellected 2 or more verts.
