The Aggregated Model
Interference checking between models created in different native formats is normally very difficult to process using a CAD tool. The challenge is even bigger if laser scan data point cloud data needs to be used in same project.
An aggregated model is easiest to create in design review software, like Navisworks, that supports all commonly known CAD file formats, IFC, Step etc as well as different point cloud file formats.
After the aggregation of different models and publishing into one model, Navisworks Freedom, the free viewer, can be used for viewing. Navisworks can also show the construction of aggregated models, the user can easily turn on and off different disciplines or transparency can be changed as well as easy generation of sectional views.
