Free-Hand Drawing at Scale Arrette is an iPad app for urban designers who want to draw free hand while maintaining a measurable drawing scale. Arrette gives designers a simple, familiar environment for anyone comfortable using scale grids, straight edges, protractors, and other traditional scale drawing tools. Unlike traditional vector drawing tools, which require years of experience to gain a mastery of the medium, Arrette can be learned within a few hours. Using Arrette on any iPad with iOS 6 or later, an experienced urban designer can create and share new designs on their iPad, importing their previous drawings, maps, and photographs from email, Dropbox, or photo albums. Designs can be shared with other Arrette users or with stakeholders who do not carry iPads. Drawings can be exported and shared in PDF, PNG, or JPEG format for easy consumption on all digital devices including Macs and PCs.
