The computer-aided design and drafting (CADD) is the use of computer technology for design and design documentation. CAD software replaces manual drafting with an automated process.
CADD software should be differentiated from computer-aided design (CAD) software. CADD systems are CAD systems with additional drafting features enabling the user to insert size annotations and other notes into a design.
