They've been modified from their original iterations, the version you see in the screenshots is what the outdoor area will look like in the final ver, for the most part.
I think it's crazy for the model editor to require such a ridiculously
large screen to run. I wonder whether there is a way to get
around that (like a "lite" version). I'll look for it...
I've been using brushes for those large pipes since they need to be in forms that no props are, and then building some geometry around the smaller prop_ pipes.
I'd make my own props, but Softimage won't even run on my computer since the screen is too small D:
