So, I probably should have posted in here, but I guess that's why I posted in the "newbie" forum...haha....i'm a newbface.

But yea. This is what I said:

So....here's the deal, I've used sketchup for awhile and whenever I have an issue I to look around for an answer, and normally I do find one.

But i'm not sure how I should go about looking for an answer to this question.

So, I can't use the follow me tool because of the "bug" that sketchup has because it will twist, so that's out of the question.

I am trying to extrude the part of the building that is connected with arrows, but its a weird surface with a bunch of curves in it. Is there any way that I can extrude it?

red, green, blue, dotted lines are axis. black dotted lines are lines not on the axis. curved lines are in solid black.
