SketchUp Animation - "Erection of a Structural Steel Staircase"

This is a simplified "construction sequence" of a structural steel staircase. I output the animation at 2x of this size and later reduced it by half in VirtualDub, hence the better anti-alias quality. For more info, visit my blog post at

Again, I don't claim the sequence is 100% by-the-book.
