Autocad — 2013
Some of the notable new features in AutoCAD 2013 include:
For drafting productivity, the command was overhauled. In previous versions, creating an array was a multi-step command-line process. AutoCAD 2013 introduced a more modern, contextual Ribbon interface for arrays. Users could now create associative arrays (rectangular, path, and polar) and edit them dynamically using grips. This "live" preview made it significantly faster to pattern objects along a path or distribute them in a grid. autocad 2013
