Free DXF viewer for Android and Windows

Updated 16 October 2026 By the tool room at Saptasati Industries 3 min read

DXF is how 2D drawings still travel: laser and wire-cut profiles, flat patterns, hole layouts and full drawing sheets. Most of a real drawing sits inside blocks and dimension objects, so a viewer that only reads loose lines shows half a sheet.

What PartLens does with a DXF file

• The whole sheet — lines, polylines with arcs, circles, ellipses, splines, blocks (nested too), dimensions, text and hatch outlines.
• Exact snapping — circle centres and line ends are the drawing's own numbers, not points picked off a picture.
• Units from the file's header ($INSUNITS).
• DXF export — PartLens also writes DXF from sections and 2D views of 3D models.

Open a DXF file

1. Get PartLens free from Google Play or as a Windows download.
2. On Android: Tap the file in WhatsApp, Gmail, Drive or your file manager and choose PartLens under Open with, or open PartLens and tap Open.
3. On Windows: Install the free Windows app, then double-click the file, drag it onto the window, or use Open CAD….

Nothing is uploaded: the file is read on your device, with no account.

What about DWG?

DWG is a closed, proprietary format, and PartLens does not read it rather than ship a half-correct reader. Every program that saves DWG can also save DXF; ask for that, or convert on a PC.
