SW to Acad DWG scaling error

I'm exporting slddrw files to Acad dwgs and I'm experiencing odd scaling errors. This happens on both assemblies and individual detail drawings. Everything measures perfect in the SW files but is off in the Acad files. Has anyone else out there experienced this? Is there an accuracy setting that I don't know about?

The attached zip file contains an slddrw assembly and detail as well as the Acad export.

Any help would be greatly appreciated. Thanks.
