DWG Viewer - CAD Viewer & DXF

DWG Viewer is a fast CAD viewer for DWG and DXF drawings: open 2D and 3D CAD files from AutoCAD and other CAD apps, measure, mark up and convert DWG to PDF or PNG. No sign-up, works offline.

DWG Viewer opens AutoCAD DWG and DXF drawings and 3D CAD models right on your phone. No account, no upload: every file is read on the device, so it works on site, in the field or on a plane.

Made for architects, engineers, contractors, site managers, surveyors, interior designers, students and anyone who gets a floor plan or blueprint by email and just needs to look at it, check a dimension and send a note back.

OPEN ANY DRAWING
• 2D: DWG and DXF, including drawings saved by AutoCAD and most other CAD apps
• 3D: IFC (BIM), STEP, IGES, STL, OBJ, glTF / GLB, PLY, 3MF and Rhino 3DM
• Open from Files, Google Drive, Gmail, WhatsApp, Telegram or any app's Share button
• Tap "Open with" on a DWG or DXF attachment and choose DWG Viewer
• Recent and Favorites lists with search, so the drawings you use stay one tap away
• A sample floor plan to try every tool before you open your own file

VIEW FAST
• Smooth pinch zoom and pan on large drawings
• Layers: show or hide each layer, see its colour
• Find text in the drawing (room names, tags, notes) and jump to it
• Dark or light background, fit to screen
• Orbit, zoom and pan 3D models with one finger and two

TOOLS
• Measure distance, angle, area, perimeter and point coordinates, with snapping to ends and centres
• Markup: draw and write on the drawing in colour to circle a problem or add a note
• 3D section: cut through a model to see what is inside
• 3D explode: pull a model's parts apart
• Try any Pro tool free by watching a short video

SHARE AND CONVERT
• Save the current view as a PNG image, measurements and markup included
• Convert DWG to DXF to open in other apps
• Export to PDF (Pro)
• Share the original file by email, chat or cloud storage

WORKS OFFLINE, STAYS PRIVATE
Drawings open on this phone only. Nothing is uploaded to a server, there is no account to create and no cloud copy of your files. Open a plan in a basement, on a building site with no signal or on a flight.

USE IT FOR
• Checking a floor plan, site plan or elevation on site before you build
• Reading wall lengths, room sizes and door widths from an architectural drawing
• Reviewing mechanical, electrical and plumbing drawings away from the office
• Opening a BIM model (IFC) or a 3D part (STEP, STL) a client sent by email
• Sending a marked-up screenshot back to the designer in a chat

ALSO ON YOUR COMPUTER
Need a bigger screen? The free online DWG viewer at dwg-viewer-cad.web.app opens DWG, DXF and 3D files in any browser on Windows, Mac, Linux or a Chromebook, in 2D and 3D, with the same tools and nothing to install.

HOW IT WORKS
1. Tap Open drawing, or open a DWG or DXF from another app
2. Pinch to zoom, turn layers on and off, find text
3. Measure, mark up, then save a PNG or PDF and share it

QUESTIONS
• Can I edit a DWG? No. DWG Viewer is a viewer: it does not edit or save changes to the original CAD file. Markup and measurements go into the PNG or PDF you save.
• A DWG won't open? Some very new or protected DWG files may not open; saving them again as DXF from your CAD program usually helps.
• Do I need AutoCAD? No. You need nothing else to open DWG and DXF files.
