## What is Residential Blueprints Toolkit?

Master the language of residential construction drawings with this comprehensive interactive learning studio. Whether you're a student, homeowner, aspiring builder, or seasoned professional, this app transforms how you study and understand construction blueprints.
NEW IN VERSION 2.0:
HOME DASHBOARD — Launch into a personalized home screen that tracks your learning journey. See your overall progress, daily construction tips that rotate through 30 expert insights, recently viewed drawings, and quick stats at a glance.
INTERACTIVE QUIZ — Test your knowledge with 60+ multiple-choice questions spanning 8 disciplines: General & Blueprints, Civil & Site, Architectural, Structural, Mechanical (HVAC), Plumbing, Electrical, and Fire Protection & Low-Voltage. Each quiz shuffles questions, shows explanations after every answer, and saves your best score per discipline.
PROGRESS TRACKING — Every drawing you open is automatically marked as reviewed. Category cards display progress rings so you can see exactly how much of each discipline you've covered. The Home dashboard shows your overall completion percentage.
PERSONAL NOTES — Add your own annotations to any drawing directly from the gallery. Jot down observations, study reminders, or questions for later. Notes are saved and accessible across sessions.
CORE FEATURES:
Browse 136 detailed illustrations organized across 11 disciplines — from General & Cover Sheets to Construction Details & Appendices. Swipe through a full-screen gallery with pinch-to-zoom up to 6x. Tap to toggle the overlay for a distraction-free view. Double-tap to quick-zoom.
21 ENGINEERING CALCULATORS covering Structural (beam, concrete, rebar, footing), Civil (runoff, Manning's pipe flow, earthwork), Architectural (occupant load, egress, parking), Mechanical (cooling load, duct sizing, outdoor air), Plumbing (fixture units, pipe velocity, water heater), Electrical (voltage drop, kVA-to-amps, conduit fill), and Fire Protection (Hazen-Williams, NFPA 13, low-voltage cable).
7-CHAPTER EDUCATIONAL GUIDE covering what a construction drawing set is, all 10 disciplines and their sheet numbering conventions, the complete drawing set master list (G-000 through D-003), the roles of architects/engineers/contractors, how to read a blueprint, and a 23-term glossary.
