Did you figure out how to do it? I'm having the same trouble. I have the PC version. I can't get her to jump off the poles before swinging around. What keys do you push? I've tried everything.

I tried many other ways, because I couldn't seem to make it over the collapsing floor. Actually, a square piece of floor right in front of the door she comes out of stays intact also and it may be possible to jump backwards to that and from there to the floor on the right. I haven't tried it.

Yes, but you have to jump from the righthand section of that piece of floor so you are pointed at the very corner of the broken ledge which is attached to the building, otherwise you can't make the jump. Then you take a standing jump with Lara's back against the wall and go over the small gap in the ledge. From there you can walk around the rest of the ledge and jump to the final ledge.

Sorry, I don't. Just turn around toward the back right corner floating section of floor and run and jump to it. It doesn't collapse.

I found it much easier to turn around and jump to the right ledge--it doesn't collapse. From there it's pretty easy to make your way around the ledge against the wall to the final ledge and cut scene. The walkthroughs don't mention this way of doing it.
