The capabilities of virtual systems allow users a closeness to the recreated space, while allowing a rapid flow of changes and updates of the models. Based on these premises, this article focuses on the qualitative design and evaluation of a new visualization and virtual interaction proposal based on tactical urban projects. The perceived usefulness in the field of architecture that these systems can have for understanding the three-dimensional space is also evaluated and compared with other current CAD / BIM systems. The results show a high degree of interest and user satisfaction but with a need to improve the interaction and the qualities of the contents.
