The drawing in your pocket, on site
Open a .DWG on any phone or tablet, in the browser, with nothing to install. Pinch to zoom, tap to measure, and pin a note where the problem is.

Fast on mobile data
Large drawings, still smooth
TrattoCAD reads the drawing on the server and streams only what is on screen, at the detail you need. Panning and zooming stay fluid on a laptop or a phone, even with drawings of millions of objects.

- Works in Chrome, Edge, Firefox and Safari
Measure on the spot
Tap two points to read a distance, with snaps to endpoints, midpoints and centres.
