This video reviews how Visicon's 3D Boolean Difference Operation can be used to quickly find the exact changes an architect made in their Revit models. Visicon's algorithm compares the two geometries in the models and reports back the exact geometric changes like no other solution in the market. The input to the algorithm are any two versions of Revit, IFC, ETABS or ADAPT models. You can download your free trial at https://visicon.com/.
