About CAD Viewer

This CAD viewer opens DWG and DXF drawings in the browser, so you can check a plan without AutoCAD. It helps on a site visit with only a phone, on a Mac or Chromebook, or when an email attachment needs a quick look before you forward it. Upload the file and the drawing appears on the page.

Zoom in to read a dimension, pan around a large sheet, and switch layers off to hide things like furniture or hatching and see what's underneath. The viewer is for looking, not editing. To print or share the drawing, convert it with DWG to PDF; to edit it in another program, DWG to DXF is the next step.

FAQ

CAD Viewer: questions and answers

Can I use the CAD viewer on my phone?
Yes. Open this page in Safari, Chrome or another mobile browser, choose the DWG or DXF file and the drawing appears.
Can I edit a drawing in the CAD viewer?
No, it's for viewing. You can zoom, pan and switch layers, but not change the drawing. To edit it in another program, convert it with DWG to DXF first.
How do I print a DWG without AutoCAD?
Use DWG to PDF. It makes a PDF from model space or every layout on the paper size you choose, and you print the PDF.
Is this online DWG viewer free to use?
Yes, within the usual limits. Visitors get 2 tasks in total and free accounts 2 a day, with files up to 50 MB; VIP opens files up to 1 GB with no task limit.
Is my drawing stored anywhere?
Only for an hour. It's uploaded over HTTPS, rendered in an isolated process and then deleted automatically, and nobody here looks at it.
