View, measure & mark up 2D and 3D drawings

A CAD reader that opens straight away

DWG, DXF and 3D models open in the browser on any computer, or on your Android phone. No CAD licence, no desktop install, nothing to set up.

The same drawing at your desk and on site

Check a plan on the big screen, then open it again on your phone from Files, Drive, Gmail or WhatsApp when you are on site. The app works offline.

Your file never leaves your device

The viewer reads the drawing right where it is. Nothing is uploaded to us or to anyone else, so client drawings stay private.

Try it right here

Why DWG Viewer?

Fast to open, simple to use, free for every drawing.

2D and 3D views

Switch any DWG or DXF between the flat sheet and a 3D model you can orbit, with each layer lifted apart.

Layers

Turn layers on and off to read just the walls, the wiring or the dimensions.

Find text

Search room names, tags and notes and jump straight to them on the sheet.

Measure with snapping

Distance, angle, area and coordinates that snap to ends, midpoints and centres.

Markup

Circle a problem, draw an arrow or write a note in colour on top of the drawing.

Save as PNG

Export the view with your markup as an image to send in chat or by email.

DWG to DXF

Convert an AutoCAD DWG to DXF in one click, right in the browser.

3D model formats

IFC, STEP, IGES, STL, OBJ, PLY, 3MF, glTF and Rhino 3DM, with standard views and wireframe.

Section and explode

Cut a model open or pull its parts apart to see what is inside.

Dark or light sheet

Read the drawing on black like your CAD program, or on white like a print.

Nothing uploaded, works offline

Files are read on your device, even with no signal on site. No account, no cloud copy of your drawings.

PDF and photos too

The app also opens PDF documents and photos (PNG, JPG, HEIC, WebP) next to your drawings, so a whole project folder is in one place.

Questions, answered

Something else, or a file that won’t open? Email fighttech.vn@gmail.com.

Which files does DWG Viewer open?

2D drawings in DWG and DXF, including files saved by AutoCAD and most other CAD apps, and 3D models in IFC, STEP, IGES, STL, OBJ, glTF and GLB, PLY, 3MF and Rhino 3DM. The phone app also opens PDF documents and photos (PNG, JPG, HEIC, WebP).

Does it work without internet?

Yes. Drawings are read on your phone, so you can open them on site, in the field or on a plane. The free version needs a connection only to load ads.

Are my drawings uploaded anywhere?

No. Files are opened on the device and never uploaded to us or anyone else. The app keeps a private copy so they appear in Recent and Favorites; removing a drawing from the list deletes that copy.

Can I edit a DWG file?

DWG Viewer is a viewer. You can measure, draw markup on top and export the view, but it does not change or save the original CAD file.

What does DWG Viewer Pro add?

Pro removes every ad and opens all tools, including PDF export and the 3D section, explode and measure tools. You can also try any Pro tool for free by watching a short video. Choose yearly with a 3-day free trial, monthly or a one-time lifetime purchase.

A DWG file won’t open. What can I do?

Some very new or password-protected DWG files may not open. Saving the drawing again as DXF from your CAD app usually helps. Send the file to fighttech.vn@gmail.com and we’ll take a look.

Is there a version for my computer?

Yes. The free online DWG viewer opens the same files in your browser, without uploading them.
