Browse over 100 annotated construction illustrations organized into 14 categories: House Overview & Building Systems, Project Planning & Management, Site Planning & Floor Plan Design, Exterior Elevations & Roof, Structural Systems, HVAC, Plumbing & Life Safety, Electrical Plans & Wiring, Electrical Code & Systems, Low-Voltage & Security, Residential Electrical Layouts, Site & Proximity Plans, Individual Circuit Routing Plans, and Residential Electrical Wiring Floor Plans. Every illustration zooms with a pinch gesture and can be saved to your Favorites for instant recall.
New in Version 2.0 — Three Powerful New Features:
Construction Drawing Glossary — A fully searchable reference library of 120+ terms, abbreviations, and symbols covering every construction discipline: General, Architectural, Structural, Mechanical (HVAC), Electrical, Plumbing, and Civil. Tap any term to expand its full plain-language definition. Filter by discipline with a single tap, or search the entire glossary at once.
Project Phase Checklist — Track your build from Pre-Design & Site through Final Inspection with an interactive, phase-by-phase construction checklist. Ten phases, 78 individual tasks. Check items off as work progresses; your progress saves automatically. A visual progress ring on each phase and an overall progress card keep your build on track at a glance.
Home Screen Search — A built-in search bar on the Browse tab instantly filters all 14 illustration categories by name or content, so you find the drawing set you need without scrolling.
Built-in IRC Reference — A searchable multi-chapter reference covering the construction drawing process, typical drawing sets, permit requirements, and key code sections from the International Residential Code (IRC), National Electrical Code (NEC), International Energy Conservation Code (IECC), and related standards.
18 Construction Calculators — Roof pitch, stair rise & run, room area, material estimator, concrete volume, rough opening, insulation R-value, electrical load, voltage drop, HVAC heat load, simple beam, plumbing DFU, paint coverage, tributary load, site slope, snow load, wire ampacity, and water heater sizing — all in one place.
Whether you are a homeowner planning a project, a design-build student learning the trade, or a contractor needing quick drawing reference in the field, this app delivers the visuals, terminology, and checklists you need.
