Navisworks Toolkit

Layer(s) affected:                   Varies

Alias:                                       None

Associated Commands:         None

This command will open the Navisworks Toolkit dialog box. Use the Navisworks Tools to export your HydraCAD project into Navisworks.

In order to do collision detection you must use Navisworks Manage. Navisworks Simulate does not offer collision detection.

Construction coordination using 3D Building Information Models of the facility and mechanical systems is now a standard activity. Precise location of building model components is critical to ensure accuracy of clash detection. Accurate BIM Models can be easily created from a HydraCAD project at almost any time in the drawing process. How the HydraCAD Model will appear is specified in the 3D Modeling Toolbar > 3D Modeling Options. Persistent Model

An ongoing problem with coordination has been the introduction of revised models to a Navisworks project. Each time a 3D model is made in HydraCAD, new pipes, sprinklers and fittings are created with new and unique object IDs. The first time the HydraCAD model is imported into Navisworks it is easily checked with other building components for interference.

A problem arises when an updated HydraCAD model is re-introduced to the Navisworks project. When a model is created in HydraCAD, all objects are refreshed with new IDs. Due to the revised object IDs, any previous clash reports are rendered obsolete.

A solution to this problem is to maintain a Persistent Model in HydraCAD for use with Navisworks Manage. As the HydraCAD project is modified, only the objects that have been added, edited or deleted will be changed and receive new IDs. All objects that have not been modified will retain their original IDs.

After the initial persistent model file is created with Navisworks Tools, it will be compared with the updated model made in HydraCAD. Objects within the two models that match are not changed in the persistent model. Objects that are no longer in the HydraCAD model are removed from the persistent model. Any objects in the HydraCAD model that have changed or have been added will be appended to the persistent model as new objects.
