The National BIM Standard-United States® (NBIMS-US™) doesn’t define graphical standards so the United States National CAD Standard® (NCS©) is an indispensable reference standard for the foreseeable future. As CAD and BIM are different workflows, it is necessary to better define and understand the relationship between the two standards.

NCS© Reference Standard Sheet-Centric project deliverable drivers: • Permitting/Review Process • Practitioner Liability Concerns • Owner/Client requirements • Established CAD/PDF/Paper delivery process NCS© Reference Standard Standards are needed for both information exchange
