Blocks

A Block is a self-contained region on a Sheet — a plan view, a detail, a schedule, a legend. Bedrock’s segmentation pipeline detects block boundaries and classifies each one. Blocks enable targeted comparisons — instead of comparing entire sheets, you can compare specific plan views, track changes to a detail, or isolate schedule changes from drawing changes.
