In this three-part video we see how MicroStation’s powerful referencing capabilities allow the BIM model to be shared effectively. Different floors of the building are in separate references. The typical floors are referenced multiple times, any change made on a typical floor is automatically reflected on all the typical floors. It is very easy to review multiple design options simply by turning them on and off as you will see in the entrance to this building. By moving the roof up and copying the condo reference we can add additional floors to the building.
