CAD Viewer – DWG, DXF & 3D

CAD Viewer is a fast, offline 2D and 3D CAD viewer for opening, inspecting, and measuring DWG, DXF, STEP, STL, and other technical drawings directly on your mobile device.

View and inspect your CAD files locally without uploading them to cloud servers. Whether you are reviewing architectural blueprints on-site, inspecting mechanical STEP assemblies, or checking 3D-printing meshes, CAD Viewer gives you essential inspection tools on the go.

📂 SUPPORTED CAD FORMATS

CAD Viewer supports 8 major industry formats across 11 file extensions:

• AutoCAD Drawings: DWG, DXF • Engineering & Solid CAD: STEP, STP, IGES, IGS • 3D Printing & Mesh Files: STL, OBJ, PLY • Modern 3D Assets: glTF, GLB

🔹 2D & 3D DRAWING INSPECTION

• Open CAD files directly from local storage or downloads • Smooth navigation: orbit, pan, pinch-to-zoom, and 360° rotation • Preset camera views: Top, Bottom, Front, Back, Left, Right, and Isometric • Multiple rendering modes: Shaded, Wireframe, Hidden Lines, and Transparent/X-Ray • Hardware-accelerated WebGL graphics for high-FPS rendering

📏 PRECISION MEASUREMENT TOOLS

• Point-to-point distance: measure exact lengths • Angle measurement: inspect angles between geometric faces • Coordinates HUD: real-time X, Y, and Z tracking • Bounding box: instant model dimensions and extents • Customizable units: switch between Metric (mm, cm, m) and Imperial (in, ft)

🎨 ADVANCED LAYER MANAGEMENT

For supported 2D & 3D CAD drawings, manage complex project layers with ease:

• Comprehensive layer list with instant search • Toggle visibility: show and hide individual layers • Inspect layers: colors, line types, and entity counts

🔒 100% PRIVATE & OFFLINE VIEWING

Your intellectual property stays yours. CAD files are rendered directly in your device’s local memory without uploading designs to external cloud servers. Inspect confidential engineering files and NDA blueprints safely, even without an active internet connection.

📁 EASY FILE ACCESS & SHARING

Open CAD files seamlessly from:

• Device internal storage & SD card • File managers and Downloads • Email attachments: Gmail, Outlook, etc. • Cloud storage: Google Drive, OneDrive, Dropbox • Messaging apps: WhatsApp, Telegram, etc.

🕘 RECENT FILES & HISTORY

Quickly resume work with a convenient recent-files list, built-in search, and format-based filtering (DWG, DXF, STEP, STL, etc.).

🎯 WHO IS CAD VIEWER FOR?

• Architects & Civil Engineers: Review floor plans, site elevations, and construction DWG/DXF drawings in the field. • Mechanical Engineers: Inspect STEP/IGES parts, assemblies, clearances, and manufacturing dimensions. • 3D Printing & Makers: Inspect STL, OBJ, and PLY meshes for geometry and scale before slicing. • Students & Designers: Study 2D technical drawings and 3D CAD models anywhere from your phone or tablet.

🌙 DARK & LIGHT THEMES

Switch comfortably between sleek dark and clean light themes tailored for indoor offices and outdoor field sunlight.
