This is in Acad 2013. This wasn't happening last week, and I don't know what changed. I have a small drawing file with a few point blocks with attributes and some lines I'm trying to insert into a main drawing. I've made sure that both files are set to "unitless" in the following variables:
INSUNITS = 0
INSUNITSDEFSOURCE = 0
INSUNITSDEFTARGET = 0
I've run SCALELISTEDIT on both files and reset them to "metric and imperial scales", and saved both files.
The base points in both drawings are 0,0,0. Both files are in the WCS.
I've run audit on both files. I've run purge in the main drawing to make sure it doesn't already contain a definition of the small drawing. I've rebooted the PC and restarted acad.
When I insert the small drawing into the main drawing, the points come in at the correct coordinates. But the lines connecting them and the point block attributes are scaled up by 39.3700787400 and are far away. It sounds like an international feet vs. meters thing, so I must be overlooking a setting.
