About this app

DrawingViewer CAD is a fast, lightweight 2D CAD viewer and drafting editor built for architects, engineers, contractors, surveyors, and designers on Android.

View, measure, annotate, and edit 2D CAD drawings, DXF files, and blueprints directly on your phone or tablet. Built with an offline-first architecture, DrawingViewer CAD keeps your drawings private on the jobsite—with no mandatory accounts, no cloud sync delays, and no internet required.

🚀 2D CAD Viewing & Navigation
• Full DXF Compatibility: Open standard DXF files (ASCII and binary, R12–R2018) with complete 2D entity and layer fidelity.
• DWG Preview Mode: Offline DWG preview lets you open drawings, inspect floor plans, and take measurements via embedded preview sheets. (For full vector editing, export to DXF).
• Smooth Navigation: Pan, pinch-to-zoom with spatial indexing for fast rendering.
• Model Space & Layouts: Switch seamlessly between Model Space and Paper Space layout sheets.
• Display Modes: Normal, Monochrome, Grayscale, and Night mode backgrounds to suit jobsite lighting.
• Multi-Format Import: Open DXF, DWG previews.

📏 Precision Measurements & On-Site Takeoff
• Object Snapping (OSNAP): Snap to Endpoints, Midpoints, Centers, Intersections, Quadrants, Perpendiculars, Nodes, and Grids.
• Comprehensive Measure Tools: Measure distance, area, perimeter, angle, radius, diameter, arc length, entity length, and coordinate points (ΔX, ΔY).
• Quantity Takeoff: Streamline jobsite estimating with open polyline takeoffs and numbered count takeoff markers.
• Two-Point Scale Calibration: Calibrate unscaled drawings or blueprint images to real-world units (mm, cm, m, in, ft) in two taps.
• Export Reports: Save itemized takeoff data as CSV, Excel-compatible spreadsheets (XLSX), or PDF reports.

✏️ 2D CAD Drafting & Editing Tools
• Non-Destructive Workflow: Unlimited undo/redo, crash auto-recovery.

📑 Layer & Style Controls
• Layer Management: Turn visibility on/off, freeze, lock.

🔒 100% Offline & Privacy-First
• No Account Required: Open and use immediately with no registration, sign-in, or subscriptions.
• Local Data Security: All drawing files remain strictly on your device. Your proprietary plans and designs never upload to external servers.
• Battery & Data Friendly: Lightweight native rendering engine runs smoothly without draining battery or cellular data.

Whether verifying architectural dimensions on a jobsite, reviewing mechanical schematics, or drafting 2D floor plans, DrawingViewer CAD delivers fast, reliable, and private drafting on mobile.
View, measure & edit DWG, DXF & CAD drawings offline with fast precision.
