This looks like a bad spatial reference conversion. Probably one set of data with one datum and the other with a different data or using US survey feet vs feet or using data built with one coordinate system and displayed with data projected on a different coordinate system.
I work on daily basis with ArcGIS and CAD ... I like using OnX, but only as a reference as to where a property line may be.
Yup. When I worked for a mapping company back in the 1990s , we would “warp” maps so that road intersections matched the Tiger file data we used to subsequently locate customer locations. It was basically the precursor to Mapquest etc...
