Ribbuild is Ribblr's unique streamlined pattern editing tool, built for designers and integrated directly into Ribblr ePattern. It is available to designers only and works on any device via the free Ribblr app. Ribbuild helps you create interactive patterns quickly - just enter your instructions and Ribbuild handles the rest. It applies layout and graphics, enables smart sizing, adds interactive charts and built-in video tutorials, converts units, provides automatic translation, and generates abbreviations and accessibility-friendly output. You can easily add an existing PDF pattern, too, using our Import PDF tool. It costs Gems to use the tool - it will import all your instructions and photos to make the pattern interactive. Alternatively, you can add a new design, copy your PDF lines and paste into one line in Ribbuild. You will then have to add your photos manually. Learn more in the full Ribbuild guidelines.
