WHAT IT OPENS • Every DWG and DXF drawing, from the earliest AutoCAD releases to the newest • Every sheet and layout in the set, with smooth zoom down to the smallest note • Layers exactly as the drawing defines them: show, hide or isolate any of them with a tap • Tap any line, block or wall to see its layer and properties • A 3D model inside the drawing, in a full interactive view: orbit, pan and zoom, shaded, wireframe or x-ray TURN PDF AND PHOTOS INTO DRAWINGS • A PDF plan becomes a real drawing, with true lines, arcs and text, not a picture • A photo or scan of a paper drawing becomes a drawing too, with its text recognized • Set the exact scale by typing one known length MEASURE, MARK UP AND EDIT These tools require an in-app purchase: • Measure distances, paths, areas and angles, snapped to endpoints, midpoints, centers and intersections • Mark up with clouds, arrows, lines, shapes and notes, in your choice of color • Draw, move, copy, rotate, scale, mirror and delete, with exact typed lengths and coordinates • Insert doors, windows, furniture, fixtures, trees, vehicles and steel profiles from a built in library of real world blocks • Find any word across every sheet in seconds • Save your work as a DWG or DXF, or export a PDF, image or SVG Open a file from the Files app, Mail, AirDrop or any app's Share Sheet, or tap "Open File" inside DWG Viewer.
