When you activate it, another part of the walkway will be created. Jump onto it.
A bit further you'll find another platform and the next symbol.
Activating it will create two ramps. You can now get to the very top and move further with just unlocked path.
At the top you'll find portal. Enter it and you'll unlock a possibility of creating objects (RT).
You can now create two types of objects: vertical walkways and ramps. Switch between them using RB or LB. Remember that only three objects can exist at the same time. By creating fourth object you'll make the first one disappear. All objects are hovering and can be created on different heights (left analog stick).
Use this ability to get to the other side of the precipice. It is best to create walkways at the height of your characters feet, so you do not have to jump.
Behind the gap, jump down and then go to the left. You have to create objects in the way that they won't "touch" dark blue walls. If you collide with them, you'll be moved back to the start position of this chamber.
When the tunnel lowers, turn the camera down, jump and while falling create a walkway just under your feet. Now you have to walk between moving walls. Wait until you get enough space and then quickly run to the other side.
Further way leads to the left. In order to get to the top, use the ramp.
A straight way will lead you to another large room. Go to its other side by creating walkways and enter the portal. You'll end the mission.
