Arch N Line

Arch N Line turns your phone or tablet into a professional drafting board — sketch, measure, and design architectural drawings anywhere, then export them as real CAD files.

Built for architects, designers, and anyone who needs precise technical drawings on the go, Arch N Line combines a full drafting toolkit, augmented reality visualization, and instant room scanning in one offline-first app.

✏️ DRAW & DRAFT LIKE A PRO
- Freehand and technical drawing tools — pen, pencil, marker, and smudge
- Precise shapes: lines, rectangles, circles, ellipses, arcs, polylines, and splines
- Dimensions, revision clouds, section cuts, and north arrows
- Layers and multiple pages per project
- Snapping, ortho/polar guides, rulers, and a built-in tape measure
- Set any drawing to scale (1:N) for true architectural accuracy
- Import images or PDFs as reference layers
- Full undo/redo history

📐 ARCHITECTURAL SYMBOL LIBRARY
Drop in ready-made symbols for doors, windows, furniture, fixtures, landscaping, electrical, people, and vehicles — or save your own custom symbols for reuse across projects.

📷 SCAN A ROOM, GET A FLOOR PLAN
Point your camera around a room and Arch N Line captures the space and converts it into an editable floor plan — no manual measuring required.

🕶️ AR PERSPECTIVE
View and place your designs in real space using your device's camera, so you can see exactly how a plan will look before it's built.

🗺️ SITE & MAP PROJECTS
Center your site plans directly on a real location using GPS-based map projects.

🧊 3D MODEL VIEWER
Rotate and explore your finished designs in an interactive 3D viewer, right inside the app.

📤 EXPORT LIKE A PROFESSIONAL
- DXF (CAD-ready), SVG, vector PDF, and high-resolution PNG export
- Native .archnline project format
- Print directly or share through any app on your device

🎤 PRESENTATION MODE
Walk clients or teams through your designs in a clean, distraction-free view with a built-in laser pointer.

☁️ WORKS OFFLINE, SYNCS WHEN YOU'RE READY
Every project is saved locally first, so you can draft anywhere without a connection. Turn on cloud backup to keep your projects safe and pick up where you left off.

FREE VS PRO
Get started free with up to 3 pages per project, 3 layers per page, limited AR sessions and room scans, 2 map projects a month, and 500 MB of cloud backup.

Upgrade to Pro for unlimited projects, pages, layers, AR sessions, room scans, and map projects, 25 GB of cloud backup, watermark-free high-res and CAD export, and presentation mode.

PERFECT FOR
- Architects and architecture students drafting on-site or in the studio
- Interior designers laying out furniture and fixtures
- Contractors and builders sketching quick floor plans and site layouts
- Anyone who needs professional technical drawings without a desktop CAD program

Arch N Line works fully offline for local drawing, and only asks for camera, photo, or location access when you actually use AR, room scanning, or map projects — never for ads or tracking.

Whether you're sketching a concept on-site, drafting construction documents, or presenting a finished design, Arch N Line is the architectural drawing app that goes wherever you do.
