ViewCAD Pro

ViewCAD Pro is a fast, professional DWG and DXF viewer for iPhone and iPad — fully offline, and yours to keep with a single purchase.

Open a drawing from any app and it appears immediately, rendered on your device. No upload, no conversion, no waiting on a server.

FAST BY DESIGN • Drawings are parsed and rendered locally by a built-in CAD engine, so opening never depends on your connection or a server queue • Smooth zoom and pan, even on large drawings • The recent list brings you back to a drawing in one tap

FULLY OFFLINE, FULLY PRIVATE • Works with no internet connection at all — airplane mode, site basements, remote locations • Your drawings never leave your device. Nothing is uploaded and nothing is stored on a server, which makes it a safe choice for confidential or client work • No account, no sign-up, no ads, no third-party tracking • Clear your recent list at any time in Settings

ONE PURCHASE, YOURS TO KEEP • One-time purchase. No subscription, no in-app purchases, no recurring charges • Every feature is included — nothing is locked behind a paywall • Ongoing app updates are included at no extra cost

OPEN ANY DWG OR DXF • Supports both major CAD formats used across engineering, architecture, and manufacturing • Opens files shared from other apps — Files, Mail, chat apps, cloud drives. Tap Share or Open in, and ViewCAD Pro goes straight to the drawing • Three sample drawings are included (mechanical flange, floor plan, electrical schematic) so you can try it before importing your own

LAYER CONTROL AND CANVAS • The layer panel lists every layer with its original color • Turn layers on and off to isolate the geometry that matters to you • Switch between dark and light canvas in one tap — dark for site work, light for checking against screens or paper

NAVIGATION AND CAPTURE • Pinch to zoom, drag to pan, double-tap to fit • The Fit button frames the entire drawing instantly • The toolbar fades away so the drawing fills the screen — landscape and portrait, on both iPhone and iPad • Save the current view as a screenshot to your photo library, or share the original file with colleagues

LANGUAGES English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Spanish, French, German, Portuguese, Russian, and Italian. Follows your system theme, or set light and dark manually.

GOOD TO KNOW • ViewCAD Pro is a viewer — it does not modify, edit, 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
