I just loaded ADT 2004 onto my new laptop and am working on the 3D Job From Hell (i.e., started it 2 and a half years ago in R14, upgraded it to 2004 last year, writing it back to 2002 so my client can read it on his machine, 50,000 sf site, xrefs out the wazoo, three separate buildings, etc. etc.). I was working in iso and drew a polyline along the top of a 3D object at an elevation of, let's say, 5'. I then offset the line by one inch and the offset object failed to appear. After zooming out a little I found it, at an elevation of 0! This happens predictably -- the new object is always at elevation 0, regardless of the elevation of the original polyline. Is there a toggle I need to switch? Doesn't happen on my old machine. A pain in the butt but the new machine is sufficiently superior to the old one that I'd prefer to keep working on it. Thanks,
