Leveraging Point Clouds

This entry is part 6 of 6 in the series April 2017Above: This image illustrates the transition from point clouds to modeled deliverables. These non-BIM solids were later used for com-putational fluid dynamics analysis to ensure proper airflow throughout the room. Three ways you can derive value from point clouds past the pre-design phase. By...
