Drawing Review Assistant

Drawing Review Assistant helps engineers, architects, contractors, estimators, inspectors, and project managers review construction and engineering drawings faster — right from an iPhone or iPad, entirely on-device. Import a PDF drawing set, a CAD export saved as PDF, a scanned sheet, or a photo of a blueprint. Every page becomes its own sheet, ready to measure, tag, and mark up. WHY IT HELPS Reviewing drawing sets by hand is slow: cross-checking scales, counting devices, spotting missing schedules, and building a punch list all eat into billable time. Drawing Review Assistant automates the busywork so you can focus on judgment calls. MEASURE & TAKEOFF • Calibrate scale once per sheet, then tap to measure real-world distances and areas • Tag components from a built-in library covering 10 disciplines — architectural, electrical, mechanical, HVAC, plumbing, structural, civil, fire protection, telecom, and industrial controls • Quantities roll up automatically into a takeoff table, exportable as CSV AUTOMATIC ANALYSIS • On-device OCR reads sheet text, pulls out the title block (sheet number, scale, revision, date), and runs the moment you open a sheet • Built-in checks flag common gaps — missing scale, legend, north arrow, schedules, dimensions — and feed a punch list automatically • Add your own reviewer notes alongside the auto-detected findings COORDINATION & COMPARISON • Flags likely coordination issues when tagged items from different disciplines overlap • Compare two sheet revisions side by side with a visual difference highlight MARK UP & REPORT • Draw and annotate directly on the drawing with your finger or Apple Pencil • Generate a shareable PDF report summarizing the title block, punch list, tags, and takeoff ASK QUESTIONS, GET ANSWERS Ask things like "count all electrical receptacles," "find missing dimensions," "list coordination issues," or "generate a punch list." The on-device assistant answers from what you've actually tagged and measured on that sheet — no internet connection needed, nothing ever leaves your device. BUILT FOR THE FIELD • Works fully offline — review drawings on a jobsite with no signal • No account, no cloud upload — your drawings and data stay on your device • Supports multiple disciplines in one project, so a single job can hold architectural, MEP, structural, and civil sheets side by side Drawing Review Assistant is a review companion, not a replacement for licensed engineering judgment — it surfaces what's worth a closer look so you can move through a drawing set faster.
