I finished Portal, but I have a question about 1 part. When you're making your way through the facility, there's a vent that you encounter right after the first popup missile turret you activate to break the glass. I couldn't for the life of me figure out how to get up in that vent. There were no portal compatible walls through it I could see, and a large pipe in the hallway there prevents you from using a portal to get up higher and jump in.
I ended up using a stack of the computers from the office by the turret to make a pile and jump in. I'm wondering if this is how I was supposed to do it. What did you do?
