No converting, no desktop software. SMOOTH, EVEN WITH LARGE DRAWINGS Pinch to zoom, pan, and jump to full view in one tap. Dense construction drawings stay smooth, and you don't need any CAD experience to find what you're looking for. MEASURE DISTANCE, AREA & ANGLES Measure distance, chained distance, area, perimeter, and angles. Snap to endpoints, midpoints, and centers for precise picks with your finger. Units are detected automatically when the drawing includes them. No units? Calibrate the scale and measure away. MARK UP ISSUES ON THE SPOT Pen, lines, arrows, rectangles, ellipses, and text, in multiple colors and line weights, with undo and redo.
