CAD Reader - DWG PDF Viewer

Inspect technical drawings, documents and 3D models on your Android device with CAD Reader. Import files through Android’s file picker, organize a local library and share files when needed.

CAD drawings
• Open DWG and DXF files, zoom, pan and fit drawings to the screen.
• Show or hide layers with lamp icons and toggle line weights.
• Use distance and coordinate tools and add text or line notes.
• Use advanced tools to measure area, perimeter, angles and radii, and annotate with revision clouds, arrows, shapes and photos.
• Use basic drafting tools with layers and export PDF/PNG previews. The default PDF page size is A3.

Documents and archives
• View PDF, DOC/DOCX, XLS/XLSX, RTF, TXT, CSV and TSV content.
• Open supported files inside ZIP and RAR archives.
• Select all parts together for supported multipart ZIP archives and import their contents into a folder.
• Search your library, revisit recent files and restore entries from Trash.

3D models
• Inspect STL, GLB, 3MF and supported BLEND mesh content in a 3D scene.
• See model dimensions, file size and geometry information.
• Use Pro tools to resize models along X/Y/Z in millimeters and export supported formats.

Pro and optional rewarded access
The app is free to download. Pro is available through Google Play as a quarterly or annual subscription, or a one-time lifetime purchase. Advanced measurements and annotations, DXF/CAD package export, text extraction and 3D resizing are Pro features; eligible features may also be unlocked for 24 hours with a rewarded ad. DWG comparison, LAS/LAZ point-cloud reading, 3D print export and custom watermark/watermark-free export require purchased Pro and cannot be unlocked with ads. Pro removes advertising. Current prices and renewal terms are shown at checkout.

Before you start
File parsing and viewing happen on your device. Purchase verification, advertising and related privacy services use the internet. Compatibility depends on the file version and contents; custom CAD objects or complex document layouts may not display completely. Office files use a content reader; macros and formulas are not executed. BLEND support is not a complete Blender scene/render engine. Prepare 3D print exports in suitable slicer/printer software; the app does not start a print directly.
