I finished Portal 2 and now I'm doing the achievements. How do I return to the place in which you get the "You Made Your Point" achievement? I tried with the dev console and it gets me to the right level, but I can't get the achievements. Are they like one-time-only achievements?

I made it! Here's a visual explanation.
You don't need paint for that one. Make a portal behind that cube, pull it out, then make a portal at the other end of the gap, walk through, then make another portal back into the main room.

If you've completed the game, you should be able to select "New Game" from the main menu and jump to the start of any chapter. This should make it easier to get to specific test chambers.
