Description
A grid bubble – the plain circle with reference numeral used to label structural grid lines, drawn with the number placeholder ready to edit. Simple as it is, a consistent grid bubble block keeps an entire documentation set's grids uniform in size and text position.
Place it at the ends of gridlines on plans, sections and elevations, and renumber per grid. The complete building grid layout sample on this site shows the bubbles in use across a full structural grid. A free DWG format download for AutoCAD and compatible software.
