The working canvas allows you to pan and zoom through the usual gestures, and allows multiple selection of bike parts to set their color. Adjusting the frame geometry is also easy; just touch and drag the highlighted joint points. You can also keep an eye on frame measurements and angles as you sketch your bike.
