How to continue in Chapter 6 The Fall?

Question

I'm at the control room in Chapter 6, but I have no idea how to continue. My first guess is to get across here:

So I made two portals: one high above me and one right below, so that I would get throw to the other side. But every try ends with a rather unpleasant encounter with the Aperture logo.

Any suggestions as to how to continue?

Answer 1

First tip, you're not supposed to go to that exit yet. Take a look around and try something else. You'll know when you're supposed to go up there.

Another hint:

You should get to the top floor of the office building, you'll find something inside

Solution:

Portal up to the platform like you did, and then put a portal on the sloped surface at the left of your second screenshot. Jump down from the platform and open a portal on the ground below you. This will catapult you to the upper floor of the office building

The next step after that:

Now the bridge should be extended and you should be able to jump down from the platform and use that momentum to get to the exit.

Answer 2

You must activate the elevator in the control room first. No double flinging is required.
