Quick CAD is a 2D CAD app built for phones and tablets. Draft accurate drawings on-site without heavy desktop software, add dimensions, import and export DXF and DWG files, and continue the work on your desktop CAD tool. ■ Features - Draw lines, rectangles, circles, ellipses, arcs, polylines - Smart object snap: endpoint, midpoint, center, intersection, tangent, nearest-on-edge, grid - Angle snap and ortho mode for precise angles - Dimensions (horizontal, vertical, aligned, radius, diameter) - Text annotations - Offset · Trim · Extend · Fillet - Rotate · Move · Copy · Mirror - Unlimited undo / redo - DXF and DWG import / export — works directly with AutoCAD and other desktop CAD - In-app support chat — reach the developer right from Settings ■ DWG viewer & editor Open .dwg files sent from AutoCAD, inspect and edit them, then export back as .dwg or .dxf. Dimensions and layers from the original are preserved. No desktop viewer install needed — do it on your phone or tablet. ■ Multi-language UI Available in 11+ languages — English, Korean, Japanese, Chinese (Simplified / Traditional), Spanish, French, German, Portuguese, Russian, Hindi, and more. Automatically matches your device language. ■ Who it's for - Architects, interior designers, and contractors who need to view and edit DWG/DXF on-site - Designers and engineers who prefer drawing by hand while keeping precision - Students and independent makers who need a lightweight drafting tool ■ Privacy first Quick CAD has no accounts and no login. Every drawing stays on your device. No ad SDK. Anonymous usage patterns (which tools/features are used) are collected to improve the product; no personally identifiable information is included. You can opt out in Settings. (DWG conversion is processed via the CloudConvert API and discarded immediately after.)
