Architects don't know what coordinates are. No, really. They don't. I asked one, one time, what coordinate system his file was in, because it wasn't coming anywhere close to where it should be (imagine you're doing a site design in Tennessee, and the building is coming in at, oh, I don't know, somewhere around New Guinea...). Well, when I asked, the line sounded like it went dead. So I asked, again... After hearing him clear his throat, he asked me what did I mean. I told him the survey file was appeared to be in state plane coordinates, but the building file I got from him wasn't anywhere close.... Turns out, they took a corner of the existing structure (which was demo'd by the time the proposed plans were being done), and made that 0,0,0, and arbitrarily started drawing w/ North facing up...

Dear god, make the bad men (architects) stop... I have but one wish... That architects learn what coordinates are. Then, they might actually have their CAD guys learn that you actually can rotate a view AND the UCS, and NOT just the building, so you can still draw w/ ortho, if you so choose... Drives me freaking insane. How do you do a site plan, down to the hundreth of an inch accuracy, if the freaking architect won't put the building where it's supposed to be???
