Krystal Sayers has created hundreds of 3D components and assemblies in AutoCAD 2006 from physical measurements to use in experimental assemblies and submittals. She has also made 2D drawings for electrical contractors to facilitate cable and box installation using backgrounds supplied or recreated in AutoCAD 2010, typically completing assignments within an hour or three depending on the background format. With no prior CAD experience, Krystal learned AutoCAD efficiently and her work quality allowed her employer to reduce CAD operators from three to one in under a year.
