AI Redline Pickup
AI redline pickup is the use of AI to read reviewer markups on a drawing set, whether scanned hand marks or PDF markups, and apply those changes to the CAD files.
AI Redline Pickup in practice
Floor Plan Review, annotated
A review set with redline markups: clouded changes, notes, strike-outs, and questions back to the designer.

Definition
Redline pickup is the step after review: someone marks up a set in red, and a drafter goes sheet by sheet transferring each comment into the CAD files, clouding the change, adding a delta tag, and updating the revision block. It is precise, repetitive work, and the common failures are easy to predict. Marks get missed on dense sheets, a change on one sheet is not carried to the related schedule, or the clouds and title block revisions do not match what changed. AI redline pickup reads the marked-up set, including handwriting and PDF markup annotations, interprets each instruction, edits the drawings, and produces a list of every change and every mark it could not read. The reviewer then confirms the pickup against the original markups. Ambiguous marks such as an arrow without a note or a question mark beside a dimension should come back as questions, not guesses. Nomic works in CAD on its own computer, saves real DWG files to the project in your layers, blocks, and title blocks, and checks each drawing against the code edition you name and the source documents before your licensed professionals review and stamp it. It clouds and tags every change, updates title blocks, plots the set, writes the transmittal, and flags marks it cannot read.
Examples
A scanned set with handwritten engineer markups on 22 sheets is picked up into the DWGs with each change clouded and tagged as revision 2.
A PDF markup moving a panel to the opposite wall is applied on the power plan and the panel schedule location note is updated to match.
A circled dimension with only a question mark is returned to the reviewer as an unreadable mark rather than changed.
