Phones and tablets
A phone opens Linea's companion view for photographing sketches. Drawing and modelling need a computer, or a large tablet in landscape.
On a phone
The companion lists your models. You can start a new model, rename it, make a copy, pin it or delete it, and photograph a sketch onto a model so that it waits there as a trace guide. The scale of that sketch is set later, on a computer.
On a tablet
A tablet whose screen is 1280 pixels wide or more in landscape opens the full editor. A smaller tablet, or any tablet held in portrait, opens the companion view, the same as a phone.
Linea draws best with a mouse or trackpad, so a computer is still the way to do serious work.
