Urban Network Analysis toolbox for  Rhino3D

Urban Network Analysis (UNA) Rhino toolbox offers powerful methods for analyzing spatial accessibility, pedestrian flow and facility patronage along spatial networks.  The UNA toolbox for Rhino 5 or 6 was developed in order to make spatial network analysis tools available to architects, designers and planners who do not have access to GIS and typically work on designs in Rhino. Having UNA metrics in Rhino not only allows one to analyze how a specific spatial network performs, but to also incorporate the analysis into a fast and iterative design process, where networks can be designed, evaluated and redesigned in seamless cycles to rapidly improve the outcome.

The UNA Rhino toolbox is significantly faster that its GIS counterpart, which has been available as a plugin for ArcGIS since 2012. Users also have an ability to rapidly create and edit networks from any Rhino curve objects, making network design and redesign simple and intuitive. The analytic options available to the user have expanded, offering users more precise control and flexibility in solving spatial network analysis problems.
