Hi, I have tried countless tutorials. Why is this not working? I created this outline of paths to resemble an ogee arch. Now, I want to make it fit onto the 3D grid (as shown). This should be easy! Grab each corner and snap it to the cube corners! Yet, somehow it is impossible. Yes, I already clicked "Join" in Pathfinder. I tried to "Convert to Shape" and it wouldn't allow. "Expand" is grayed out regardless of which tool I select. Please advise! I've wasted 2 days on this bottleneck.
