I apologize for not providing sufficient detail to explain my question.
This would be for an as-built plot plan of a facility. The facility is about 15 acres and has several buildings and structures.
When I take a measurement on the CAD drawing and compare it to the actual physical measurement, I find differences of a few percent to as much as 50%. The title block indicates that the drawing is to scale. I've sent the drawing back to the draftsman for corrections.
I realize that a 50% variation is unacceptable, but how accurate should we expect measurements on a drawing to be?
