Justin,
I don't know if this is relevant to your problem; but not being too familiar with the DWG editor, it had me puzzled for a while.
I'd been down the path of making sure of sheet scales and even created a "Full size" DXF/DWG sheet for exporting large items to avoid annoying error messages. I always opened the exported file in the DWG editor and used "Inquiry > Distance" to measure a couple of key elements to make sure all was OK. One day, shortly after upgrading SW and the Editor, I had a query from the workshop and went to check the DWG, it measured OK, but when I added a dimension, this was scaled 5X!!
After a bit of digging in the Editor, I found that under >Settings > Dimension Settings > Units (Tab) there are a couple of Scaling Options, the "Comprehensive scale factor" was correctly set to 1.00 but the "Linear Dimensioning scale factor" was set to 5.00 in a scrollBox. Quite why anyone would want the dimensions not to show the actual size is beyond me and seems very dangerous, I guess it must have some use (or so the programmer thought). I don't know if these setting are carried with the file, or if the setting on the openers software applies, so now I always add a couple of check dimensions to the exported file, and EXPLODE them to arrows and text so they won't be scaled whatever the settings.
