1. Executive Summary The term "ZBBZ" (坐标标注 – Zuòbiāo Biāozhù ), literally Coordinate Marking , is not a native AutoCAD command but a widely used alias or custom function (typically via LISP, ARX, or third-party plugins like Tianzheng CAD , Haochen CAD , or CAD Mini ). It enables rapid annotation of X, Y coordinates (and sometimes Z elevation) of selected points directly onto a drawing, formatted for construction, survey, or GIS outputs. autocad zbbz
