Aligns original drawings with field markups (red lines), classifies each redline (dimension change · fixture move · addition · deletion · callout), and cross-checks against approved RFIs and COs. Generates the as-built drawing set.
The engine matches each markup back to its original sheet using a vision transformer. Redlines are detected via red-channel pixel analysis + LLM segmentation.
For every detected redline:
Original drawing with the redline applied + a citation list at the bottom of each sheet pointing to the RFI/CO that authorized each change. The closeout-ready PDF.
Phase 1 supports PDF redlines only. Photos of paper redlines are queued for v1.1 (CV quality varies). Use the iPad to scan paper redlines as PDF for best results today.
