Fast. Drawings are parsed and rendered locally by a built-in CAD engine — no upload, no conversion, no waiting on a server.
Offline and private. Your drawings never leave your device. Nothing is uploaded, nothing is stored on a server — a safe choice for confidential or client work.
One purchase. No subscription, no in-app purchases, no recurring charges. Every feature is included.
Open drawings from anywhere
Tap Share or Open in in Mail, Files, a chat app or your cloud drive and choose ViewCAD Pro — the app goes straight to the drawing. You can also tap Import Drawing on the home screen to browse for a file, and the recent list brings you back to a drawing in one tap.
Built for real drawings
DWG and DXF
Both major CAD formats, as used across engineering, architecture and manufacturing.
Layer control
Every layer listed with its original colour. Tap to hide or show — the drawing updates instantly.
Dark and light canvas
Switch in one tap. Dark for site work, light for checking against screens or paper.
Smooth navigation
Pinch to zoom, drag to pan, double-tap to fit. The toolbar fades away so the drawing fills the screen.
Screenshot and share
Save the current view to your photo library, or send the original drawing file to colleagues.
Landscape and portrait
Designed for iPhone and iPad, in either orientation, with a wide landscape view for large sheets.
Your drawings stay yours
ViewCAD Pro has no accounts, no analytics, no advertising and no third-party tracking. Parsing and rendering happen entirely on your device, and the app works with no network connection at all — on a plane, in a basement, on a remote site.
Try it before you import
Three sample drawings are included so you can explore the app right away: a mechanical flange, an architectural floor plan and an electrical schematic.
In eleven languages
English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Spanish, French, German, Portuguese, Russian and Italian. The interface follows your system theme, or you can set light and dark manually.
Good to know
- ViewCAD Pro is a viewer: it does not modify, edit, measure or convert drawings.
- Very large files can take a moment to open on older devices.
- No account or personal information is required to use the app.
