Qua-kit is a web platform for viewing and manipulating simple urban geometry.
Logged in via edX platform you can work on a single design problem, share your ideas together with design proposals, view and discuss works of others.
Local clients can use qua-kit as a presentation tool. Connected to a computational server backend it can use registered remote services for visual analysis of geometry.
The platform is an open source project; therefore, everyone is welcome to contribute.
