What, are you saying that accurate as-builts are routinely not done?! Quel surprise!

One of the problems with 3D piping software is that everyone has to religiously follow all the software-dictated procedures in order for it to work properly (because a computer only knows ones and zeros). Of course, anything short of dictator-like control over the operators' activities can possibly cause errors that make the whole system go crashy. Or maybe it was a Windows DLL conflict. Or a power spike. Or a random error generator built into the network (OK, now I'm stretching the concept a bit far).
