From the developer:
Modelur is an easy-to-use, yet very powerful parametric urban design software tool, developed to help you quickly create conceptual urban massing. It calculates key urban control parameters on the fly (e.g. FAR or required number of parking lots), delivering important information while design is still evolving. This way it fosters well-informed decision making during the earliest stages, when design decisions have the highest impact.
